The Survey Link Extension enables you to download data from survey data collectors and

2 | Chapter 1 Introduction

convert raw data into .fbk files. Survey figure editing commands are now available.

Pipe Networks A new command enables you to select a series of pipes and structures in the drawing, and then rename or renumber them. You can use a spanning label for pipes displayed in a profile. You can use a pipe end cleanup option in profile views.

Labels You can now label most AutoCAD Civil 3D objects that are contained within an Xref. For line, curve, and spiral labels on alignment, parcels, and general line and curve labels, there are new label anchor points such as start, middle, and end. General line and curve labels can now be included in parcel tables.

Surfaces You can now reorder surface operations and can weed points to control the number of points that are used when creating a surface (TIN). This feature has been enhanced with more intelligent memory management, data restriction for improved performance, and point weeding to achieve a simplified surface which results in improved performance for large surfaces.

Grading You can have dynamic feature lines from alignments,profiles, and corridors. You can name feature lines for easier identification, and can apply styles to a selection set of feature lines. You can prioritize feature line styles to determine split point elevations and can create a feature line from the alignment geometry. Numerous new feature line commands make it easier to edit elevations.

Alignments You can associate agency-specific standards during the alignment and profile design process to ensure compliance with standards. Additionally, you can use a new post-design error-checking mechanism, which checks the alignment and profile geometry for entities that violate the associated standards. You can now control label styles for different alignment and profile geometry points in order to label these in different ways. You can also label superelevation critical points along an alignment. You can create alignment entities using the best fit tools.

Profiles You can create stacked profile views and anchor superelevation band labels to superelevation diagrams. You can associate agency-specified standards during the alignment and profile creation process. Also, you can use the error-checking mechanism which checks for violations of the associated standards. You can create profile entities using the best fit tools.

Corridors You can use survey figures, grading feature lines, polylines, and pipe networks as subassembly targets in a corridor. The View/Edit functionality has been enhanced.

Mass Haul A new Mass Haul Diagram wizard is available to generate a mass haul diagram that remains dynamic in relation to the corridor model.

Google Earth You can publish render materials on entities for display in Google Earth. Also, you can import elevation data in a current Google Earth view into AutoCAD Civil 3D as a mesh.

Designing with Objects

2

The underlying object model in AutoCAD Civil 3D creates some major efficiencies in the engineering design process. Because of this model, changes to one object can affect related objects, and object styles can control many aspects of object appearance and behavior. This chapter describes both the object model and the AutoCAD Civil 3D user interface for working with objects.

Object Model The architecture of AutoCAD Civil 3D ensures that each object, such as an alignment or a parcel, has a standard set of attributes and relationships to other objects. These objects are “intelligent” in the sense that they automatically react in predictable ways to changes in related objects. As a result, you do not need to spend hours ensuring that design revisions are transferred correctly among surfaces, alignments, profiles, sections, labels, tables, and other objects. The tedious tasks of redrafting and relabeling are eliminated. Design options and “what if” scenarios can be created more easily and analyzed with precision, resulting in significant process improvements.

Object Relationships The following illustration shows a simplified view of object relationships and data flow in an AutoCAD Civil 3D drawing:

Object relationships and data flow

Object Relationships | 13

Field survey data creates figures and points that can be used to generate an existing ground surface and parcels. This surface is referenced as other objects are created in the design process, resulting finally in a designed surface. Parcels, existing ground surfaces, pipe networks, and gradings can be created independently, or from data sources not shown in the illustration. Such objects are usually linked to other objects during the design process, if not at the beginning. The object type with the most complex set of relationships is the corridor, because it requires data from an alignment, profile, and assembly. Changes to any object automatically flow along the arrows to dependent objects, with predictable results. For example, if you correct the elevations of an existing ground surface, updates flow to any related grading objects, corridors, profiles, and pipe networks. As a result, all values represented in labels and tables are also updated. In the design process, after you create an alignment you can create many profiles and sections. However, the display of these in profile views and section views is optional and separate from the flow of data required to create the final product—a designed surface. Similarly, the data from objects, such as parcels and alignments, can be output to a table or report if desired.


Object Interface The user interface of AutoCAD Civil 3D reflects the object architecture of the application. The major elements are shown in the following illustration:

AutoCAD Civil 3D User Interface

The following notes describe the numbered items in the illustration: 1 Toolspace. For object management. Uses four tabs: Prospector; for navigating through the object collections, Settings; for managing styles and settings, Survey; for managing survey data, and Toolbox; for generating object reports. 2 Item view. For a list view of the contents of the selected folder or a graphic view of the selected object. 3 Layout tools. For creating and editing objects, such as gradings or alignments. 4 Standardized menus. For consistent access to the full range of commands.

Object Interface | 15

5 Tabbed property editors. For modifying individual objects and their attributes. Each part of the user interface is described in more detail in the following sections.

Toolspace for Object Management The Toolspace window provides an object-oriented view of your engineering projects. The window is divided into four parts or tabs: Prospector tab, Settings tab, Survey tab, and Toolbox tab.

Prospector Tab On this tab, all of the objects in a drawing or project are arranged in a hierarchy that you navigate in standard, Windows Explorer–like fashion. To access this tab, click General menu ➤ Toolspace. To view all the collections in the Prospector tree, select Master View from the list at the top of the Prospector tab. The collections available here are Open Drawings, Projects, Data Shortcuts, and Drawing Templates. Note that Projects lists projects available after you have logged into an Autodesk Vault server and Vault database. A site collection includes objects that are related to one another because they share topology. The following illustration shows a typical structure. The Oak Street site folder contains collections for alignments, grading groups, and parcels that belong to the site. The Parcels folder contains the parcel objects defined for the Oak Street subdivision. Note that the view selected is Active Drawing.

Settings Tab On this tab, styles are organized for different object types. Even in a blank drawing, most of these styles are present in a standard hierarchy. You can create and modify styles in a drawing, then save it as a template. Subsequent drawings based on the template will automatically have the same set of styles available. You can modify object, label, and table styles. You can also control settings for drawings and commands. To access this tab, click General menu ➤ Toolspace. In the following illustration, label and table styles for parcels have been defined:

Each type of object can have an unlimited number of styles.

Predefined label styles can be applied to any parcel in the drawing.

The Settings tab in Toolspace


Survey Tab To access this tab, click Survey menu ➤ Open Survey Toolspace. This tab displays survey project data, organized within databases for survey projects, equipment, and figure prefixes. The project databases record the survey points, networks, and figures. The equipment databases record standard deviations and other operational parameters of individual pieces of survey equipment. The figure prefix databases record the conversion routines that are applied when creating lots, buildings, or other figures from survey points.

The Survey tab in Toolspace

The contents of the Survey tab are not specific to a drawing. This tab reflects the survey data in your AutoCAD Civil 3D Projects folder, so it facilitates access to survey data from multiple drawings. The surveyed points and figures in a project can be converted to Civil 3D points and parcels.

Toolspace for Object Management | 19

Toolbox Tab To access this tab, click General menu ➤ Toolbox. This tab organizes reports for each object type. The reports provide useful engineering data from a drawing in a compact, portable format. AutoCAD Civil 3D includes many standard reports. Some are in LandXML format, with predefined or custom XSL style sheets. Other reports are .NET format, with custom dialog boxes that allow you to select the data and various options.

The Toolbox tab in Toolspace

You can add your own reports to the Toolbox menu. These reports can be in a variety of formats, including XML, VBA, COM, or .NET.


Menu Standardization The menus in AutoCAD Civil 3D are designed to be as consistent as possible for all objects, making it easy to find the command you are looking for. This standardization reflects the fact that the workflows for creating, editing, and annotating various objects are quite similar. The object creation commands are at the top of the menu structure, because logically they are the first steps in any workflow. They are followed by the editing commands, and then, the annotation commands. Note that all feature menus provide access to the labeling and table creation commands.

Comparison of the Pipes, Parcels, and Alignments menus

In this release of AutoCAD Civil 3D, the Grading feature line editing commands are also available on the Parcel and Survey menus. Use these commands to edit parcel geometry as well as parcel elevations. You can also use the feature line commands to edit survey figures, including control points.

Menu Standardization | 21

Comparison of the Parcels and Survey menus

AutoCAD Civil 3D comes with several workspaces that you can use as-is or change according to your preferences. Workspaces are sets of menus and toolbars grouped together to enable you to customize workspace settings. AutoCAD Civil 3D workspaces include Civil 3D Complete, Design, Annotation and Drafting, Survey and Topographical, and Visualization and Rendering. For more information about using workspaces, see the Help system. The Annotation menu in the Annotation and Drafting workspace is designed to facilitate the creation of annotation labels and tables. The Annotation menu provides access to all label and table commands. The feature menus, such as the Pipes, Parcels, and Alignment menus, also include options for the creation of labels. To modify label styles and settings, use the Add Labels command to access the Add Labels dialog box. This command is located on both the feature (Civil 3D Complete workspace) and Annotation (Annotation and Drafting workspace) menus. For a quicker method to add labels when your styles are already set up, you can use the direct creation method for specific label types. For example: Parcels menu ➤ Add Parcel Labels ➤ Single Segment. To access the Add Labels dialog box to edit or create features label styles, use Parcels menu ➤ Add Parcel Labels ➤ Add Parcel Labels. See the Help system for instructions on creating labels for features and objects.


Annotation Label and Table menus

Menu Standardization | 23

Shortcut Menus AutoCAD Civil 3D uses shortcut menus extensively. These menus are displayed when you right-click either one or more objects in the drawing, or an individual item in Toolspace. You use shortcut menus for quick access to common functions and commands. Here are two examples from the Prospector tab. The menu on the left is displayed when you right-click an alignment object on the Prospector tab. The menu on the right is displayed when you right-click a parcel.

Shortcut menus for an alignment and a parcel on the Prospector tab

The options on the shortcut menus on the Settings tab are also very similar for different object types.


Layout Tools AutoCAD Civil 3D provides separate dialog boxes, called Layout or Creation Tools, for designing surfaces, alignments, grading, and other features. Each layout tools dialog box provides access to object-specific design and editing commands in a floating dialog box.

Layout tools for Grading, Alignments, and Pipe Networks

Consistent Editing Methods Object editing in AutoCAD Civil 3D uses an approach that is quite consistent for all objects. The main editing tools are described in the following sections.

Item View When you click an object or an object collection on the Prospector tab, for example, Points or Alignments, an item view appears. An item view can be either a list view or a graphical view, depending on the object selected.

Layout Tools | 25

The item view presents a table in which you can review and edit data for each object in the selected collection. For example, if you select a point group, the item view table includes a row for each point in the group.

Click a table cell to edit the value.

Item view showing a group of points

Grips When you select an object in the drawing, grips appear on the object. You can use these grips to click and drag the object to a new location. For example, when editing alignments, you can use grips to move points of intersection or points of line-arc tangency.

Direction of drag

Editing an alignment by dragging the grip at the midpoint of a curve


When you use a grip to drag a label object to a new location, a round reset grip appears. You can click this round grip to return the label to its original location. No matter how many times you have moved the label, the reset grip will restore it to its original location.

Use the round grip to reset label location

Panorama Window Some object types, such as alignments and profiles, use the Panorama window to display a table of entities that make up that object. The Panorama window is a floating, dockable window that you can keep open as you work. It can include several tables, called vistas, on different tabs. Panorama data shown in black text can be edited; data shown in gray text cannot be edited.

Consistent Editing Methods | 27

Property Editors When you right-click any object on the Prospector tab, and then click Properties, you can view all the AutoCAD Civil 3D properties of that object, and edit some of them. These properties typically include the styles, labels, related objects, and some structural details of the current object.

AutoCAD Properties Editor When you right-click an object in the drawing, and then click Properties, the AutoCAD Properties dialog box is displayed. You can use this dialog box to review and edit AutoCAD properties, such as the layer on which the object is drawn. You can view the style assigned to the object, and can also change it here. You can also edit an object style on the Settings tab of Toolspace. Right-click the object style. Click Edit to open the Style dialog box.

Now you will explore the workspace settings. You can customize the workspace menus to suit your particular tasks or preferences. In the lower right of the Civil 3D interface, click the Workspace Switching icon and select Annotation and Drafting and observe how the menus are reorganized.

5

Select the Annotation menu. Note the commands for adding labels and tables. This menu facilitates the labeling process during the drafting stage of your project. Experiment with the workspace settings and customize them for your design needs. Click again to open the Workspace Settings dialog box. Use this


dialog box to customize the order and display of the settings.

Standard Controls for Styles and Labels Every AutoCAD Civil 3D object has a style assigned to it. These styles are created, assigned, and managed in a consistent way for all objects. All objects have an object style and can have one or more label styles. Some objects have table styles as well. You can browse the collections of styles in a drawing, on the Settings tab of the Toolspace window, as shown in the following illustration:

Style collection folders on the Settings tab of the Toolspace window

To create a new style or to edit an existing style, right-click the style on the Settings tab, and then click Edit. The Style dialog box for labels is called the Label Style Composer. It contains a preview window that makes it easy to adjust label location and appearance.

Standard Controls for Styles and Labels | 33

There are many ways to open the Label Style Composer: ■

Right-click an existing style and click Edit.

■

Right-click an existing style and click New.

■

Right-click a label style type and click New.

■

You can also access the Label Style Composer from the Label Style Control, which is available in many dialog boxes.

You can also access the Label Style Composer while working directly in your drawing. To quickly access the composer while in the drawing, select a label. Then right-click and select either Properties or Label Properties. In the AutoCAD Properties palette, click the label style to display a list of available styles. For more information about styles and labels, see the chapter Using Styles and Settings (page 39) in this guide.


Precision Layout Strategies When creating objects, such as horizontal alignments, parcels, and profiles, you may need to use several different methods. Sometimes you want to draw quick freehand versions, other times you have specific distances and angles to enter. AutoCAD Civil 3D supports both methods of working. The main layout tools have settings that you can use to control some design elements while you draw each object. For example, when drawing alignments or profiles, you can create a series of linked tangents and add curves later, or you can have curves of standard dimensions inserted at each tangent intersection as you draw. Similarly, you can specify a default area for each parcel and a minimum frontage distance. You can also use the transparent commands to specify precise point locations while you are laying out an object. From a current point in an alignment or parcel, you can specify the next point using standard surveying methods, such as angle and distance, northing and easting, latitude and longitude, or point number. As shown in the following figure, for a profile, you can specify a point by various methods, such as station and elevation or grade and distance. In each case, you use the command by entering a short code on the command line (for example, ‘bd for bearing and distance) or by clicking an icon on the Transparent Commands toolbar.

Object Building Blocks Corridors and pipe networks share a similar complex structure, in that both objects are built up from standard components. These components exist in a catalog, and you can modify them to create additional components.

Precision Layout Strategies | 35

Corridors A corridor is created from one or more assemblies, which are standard roadway cross-sections. You design an assembly from subassemblies, such as lanes, curbs, shoulders, and ditches. The subassemblies are provided in a set of catalogs, which you can review by clicking General menu ➤ Catalog or General menu ➤ Tool Palette Window.

Roadway assembly (left), with subassemblies shown in a tool palette (right)

Each subassembly has a defined cross-section, and some subassemblies automatically adapt to their location. For example, the slope of a road lane changes as superelevation is applied, and a side slope automatically creates either a cut or fill slope, depending on the relative elevation of the existing surface. The dimensions of a subassembly, such as the width of a lane or the height of a curb are stored as properties. If you want to create a new subassembly based on an existing one, use this simple procedure: 1 Right-click a subassembly in the Tool Palette, copy it, and paste it. 2 Right-click the subassembly that you copied and click Properties. 3 Rename the subassembly and modify the numeric parameters. You can also create custom subassemblies from AutoCAD polylines. In this case, you must also specify the subassembly behavior within an assembly and in the process of corridor creation. You can define custom subassemblies and their behavior using Visual Basic for Applications (VBA) scripts, then use the AutoCAD Civil 3D COM application programming interface (API) to link these to the main application.


A subassembly definition references point, link, and shape codes. Points are the vertices of the subassembly, and they can be attachment points for adjacent assemblies. Links are the line segments or curves between the points. Shapes are two-dimensional polygons that represent the cross-sectional shape of the subassembly. The following figure shows a coding diagram for a Basic Curb and Gutter subassembly:

Pipe Networks A pipe network is constructed from various pipes and structures that appear in a parts list. You can see the available lists on the Toolspace Settings tab by expanding the Pipe Network ➤ Parts Lists collection. AutoCAD Civil 3D includes a utility called Part Builder, which you can use to edit the dimensions of parts and create new ones. You can create a new part by saving an existing one with a new name, and then modifying its dimensions in various tables.

Using Styles and Settings

Styles determine the display format and some aspects of the behavior of objects and their labels. This chapter explains how you can use various settings and the versatile set of styles in AutoCAD Civil 3D to establish CAD standards and promote efficiency at every stage of the design process.

Managing Styles You can use styles to control object appearance and behavior, with flexibility and ease, and to establish design standards. If you are the CAD manager in your organization, you may find that time spent creating styles for others to use pays off in terms of efficiency and standards compliance. AutoCAD Civil 3D is an object-oriented program that works with intelligent objects. The objects reference a style, which can be changed at any time. Any style can be copied by dragging it from one drawing to another. The new drawing knows where to put that style in the Settings tree. You can then apply the new style to existing objects. Any label style can be copied by creating a child style. A child style derives its default settings from its parent, the existing style. To create a child style for a label, on the Toolspace Settings tab, right-click a label style. Click New. In the Label Style Composer dialog box, make changes to the settings as desired and click OK. The child style will appear underneath the parent style in the Settings tree. See the Labels and Settings (page 57) exercise at the end of this chapter. You can use styles to manage the display of objects at different phases of a project. In the following illustration, the upper drawing uses surface and parcel styles appropriate for a preliminary layout, while the lower drawing uses different styles for the final presentation:

40 | Chapter 3 Using Styles and Settings

Types of Styles AutoCAD Civil 3D includes styles for objects, their labels, data tables, and the bands that annotate profile views and section views. Each of these styles is described in the following sections.

Object Styles Each object type includes a Basic style. Use this style as it is, or as a basis for building custom styles. You can create styles to meet the needs of a particular project, a group of users, or any other design requirement. Groups of styles can be collected into a template (.dwt) file, so that all drawings based on that template share the same style configuration. All object types have similar style controls, and a similar set of style collections on the Toolspace Settings tab. You access the style editing dialog boxes by right-clicking one of the styles and then clicking Edit. The following illustration shows some common style editing tasks for points, surfaces, and alignments:

Types of Styles | 41

1 Point style: using a custom marker 2 Surface style: smoothing contours 3 Alignment style: changing the color of the line components

Editing the style for three different types of objects


In addition to feature-specific styles, AutoCAD Civil 3D includes multipurpose styles that apply to several objects. Most of these styles apply to grading objects and corridor assemblies, and control the appearance of components, such as markers, feature lines, and slope patterns.

Label Styles Labels are associated with many objects, and their content is updated whenever the object itself is changed. Labels are also controlled by styles. You can modify the label styles in the same way that you modify the object styles: right-click a style name on the Toolspace Settings tab, and then click Edit. You can create and save label sets for alignments, profiles, and sections, which allows you to apply multiple label types in one operation. For example, an alignment label set could include labels for major stations, minor stations, and geometry points. Labels can include text, blocks, lines, ticks, and leaders. You can easily create labels and preview their appearance in the Label Style Composer dialog box, as shown in the following illustration:

Label Styles | 43

Alignment station labels and parcel area labels appear in the drawing as they appear in the preview of the Style Composer.

Previewing customized label styles for alignment stations and parcel area


Table styles can also be customized.

When composing a label style, you work with the following types of attributes: ■

Location. Controls the location of the label in relation to the object.

■

Text. Specifies which object data is displayed, and sets the size, color, and font for the text.

■

Appearance and Visibility. Defines the bounding box, color, lineweight, linetype, and other aspects of label appearance, and sets the visibility of any of the label components.

■

Dragged State. Determines how a label changes if it is dragged away from the default location to a place where it is more readable. For example, you can specify the addition of a leader line with arrow.

■

Plan Readability. Automatically rotates any upside-down label text so it is readable in plan view. Otherwise, if labels are oriented in relation to an object, they might be displayed upside-down.

■

Orientation. Sets the rotation angle of the labels in relation to the object you are labeling, the current view, or the world coordinate system (WCS).

Setting the label style defaults provides an efficient way to standardize some key aspects of label appearance and behavior for all objects in the drawing. To review and edit these defaults, right-click the drawing name on the Toolspace Settings tab and click Edit Label Style Defaults. All label text is controlled by the Text Component Editor. To access the Text Component Editor, in the Label Style Composer dialog box, click the Layout tab. Select a component from the Component Name list, or create a new text component. Under Text, click the Value column for Contents, and then click . You can use this editor to simultaneously edit the text for an entire group of labels.

Label Styles | 45

Use the Properties list at the top of the dialog box to specify which object property to include in the label. For example, a parcel area label can include properties such as the parcel area, perimeter, number, and street address. Each property component can include character strings and data codes, as shown on the screen on the right. After you select a property to include, use the table on the left to specify the format of text inside the double brackets (). When you finish modifying the values, click the right arrow at the top of the dialog box to send the updated component to the screen on the right. Use the screen on the right to modify the standard text strings outside the brackets and to cut and paste entire components.

Managing Label Styles Use the AutoCAD Properties palette to manage most labels. The palette displays the Standard AutoCAD properties and also the label properties such as Label Style and whether the label is visible, flipped, or pinned. You can simultaneously edit an entire group of labels. For example, you can create additional label text for inclusion on all labels by performing a single action. Some types of labels, such as station labels, are group type labels. To edit a group of labels, right-click a label, which highlights the group, and click either Label Properties or Properties to access the AutoCAD Properties palette. Also, you can select and edit a single label. To edit a single label within a label group, use Ctrl+left-click to select a label. Right-click the label and click either Label Properties or Properties to access the Properties palette. To select more than one label (subentity) within a group of labels, continue to press Ctrl and click additional labels.


You can use the Style Selection menu in the Properties palette to bulk-edit label properties. This is a convenient method of editing labels without having to navigate to the Toolspace Settings tab. You can quickly create, edit, or copy styles while working directly within the drawing.

Select the Edit/Create option to open the Select Style dialog box where you can create a new style, copy the currently selected style, create a child style, or edit the currently selected style using the Label Style Composer. You can now directly edit or change a label style using the Edit Label Style option. In the drawing, select the label to edit. Right-click and select Edit Label Style. You can also edit an existing label style in Toolspace. In Toolspace, on the Settings tab, right-click the label style you want to edit and click Edit. Use the

Label Styles | 47

Label Style Composer to edit the label. In the Label Style Composer, click to access the Text Component Editor.

Table Styles AutoCAD Civil 3D provides automated data tables for points, surfaces, parcels, alignments, and quantity takeoff. As shown in the following illustration, these tables provide a concise display of object data as an alternative to using object labels. The table styles control the data properties and the displayed components of the table. Data properties include the data format, order of columns, text style, and whether the table title and column headers are repeated if the table is split. Display components include the borders, separators, fill, and text. You can control the visibility, color, linetype, and scale of each component.

Example data table for the Ridge Road alignment

Table Tags Use the Table Tag Numbering dialog box to set the default starting number and increment options for table tags. To access the Table Tag Numbering dialog box, navigate to the Toolspace Prospector tab. Then, right-click the drawing name, and select Table Tag Numbering. You can also access this dialog


box from the Add Labels dialog box. You can use General line and curve labels alone or with parcel segment labels to create a table. The table tag settings for segment labels are no longer controlled by the site and can be found in the drawing settings, DWG node and is drawing-wide. By default when creating table tags, the settings control the starting number, and increment number.

Use this dialog box to set your table tags automatically

Note that duplicate tags are not created unless you manually create them with the EditParcelTagNumbers command. When table tags are created, it prevents the creation of duplicate tag number within the drawing. When renumbering table tags, you can create duplicates by changing the starting number or increment in the settings (table tag renumbering section of the dialog). Table tags support the following tag mode labels: general line, general curve, parcel line, parcel curve, alignment line, alignment curve, and alignment spiral.

Band Styles Profiles and sections are displayed in a graph format. These profile views and section views can be annotated with data bands along the top and bottom of the grid. Each band marks significant points along the length of the profile

Band Styles | 49

or section. For example, in a profile view, you can have separate bands for vertical geometry, horizontal geometry, superelevation data, and pipe networks. The following illustration shows part of a profile data band above a horizontal geometry band. In the profile data band, at each major station you see the elevations of the existing ground and finished grade profiles. The horizontal geometry band shows the location of a curve and some engineering data about the curve.

Part of two profile view data bands

Separate band styles exist for each band type. In each style definition, you can specify what data to display and details of the band format, such as the height and position of the band (above or below the grid), and the color of components, such as borders and labels. If you want a standard set of bands for use with profile or section views, you can define these as a band set and apply them as needed.

Profile and Section View Styles You modify the appearance of a profile view the same way you modify the appearance of other objects, by changing its style. The profile view style controls the format of the graph on which the profiles are displayed, as well as the title and annotations on the axes. Customizing profile view styles is a good example of how styles can be modified for different stages of your project. In the design phase, you may use one profile style that has few grid elements and limited annotation. By limiting annotation and grid elements you reduce drawing size and improve drawing performance. During the plotting stage of the design, a second style may be used that includes extensive annotation and uses more graph elements


than the design style. For more information about profile and section view styles, see the AutoCAD Civil 3D Help.

Using Styles with Layers Most objects in AutoCAD Civil 3D have several components. For example, a surface includes contours, triangles, and points. You can control how these components are displayed either by using layers or by setting the display properties directly in the object style. You use the Layer Properties Manager dialog box or the object styles dialog boxes respectively to do this. The Display tab of the object styles dialog boxes provides a number of settings that are similar to those in the Layer Properties Manager dialog box, such as visibility, color, linetype, and lineweight. This duplication means that you can control object appearance using only styles, only layers, or a combination of the two. Display properties defined in the object styles dialog boxes override the settings defined for the drawing layers in the Layer Properties Manager dialog box. For example, you can use two different styles to distinguish the display of existing ground and finished grade surfaces, even if they are drawn on the same layer. The following illustration shows how you can use both style settings and traditional layers to control the display characteristics of an object. The style shown in the upper drawing directly modifies the color and visibility of the

Using Styles with Layers | 51

surface components, so that the surface points are turned on and colored red, even though the layer on which the points are drawn (0) is turned off and colored white in the Layer Properties Manager dialog box. The style shown in the lower drawing assigns the surface components to layers already defined in the drawing. In this case, the color of the major and minor contours is set by the C-TOPO-MAJR and C-TOPO-MINR layers.


Visibility and color of the surface components are controlled by settings on the Display tab of the Surface Style dialog box.

Visibility and color of the surface components are controlled by the layer assignment.

Managing object appearance using style settings (above) and layers (below)

Using Styles with Layers | 53

Label Objects Most labels are implemented as independent label objects and are not highlighted when the parent object is selected. Label object properties are separate from the parent object. You can use the LIST command to display the label properties. Label objects can include references to other AutoCAD Civil 3D objects by including Referenced Text components. The layer behavior of label objects is different. For example, their new default layers are specified in the Drawing Settings and can be changed using the AutoCAD Properties palette (rather than modifying the label style with the Label Properties dialog box). You can control the behavior of labels in one of two ways, by referencing either the layer in the style or the layer that the label resides on. In previous releases of AutoCAD Civil 3D, all group type labels were subentities of the parent object. If the parent object was frozen, the labels would disappear with the frozen parent object. Independent object labels are no longer subentities of the parent object. However, if you desire to control the object layer in conjunction with a parent object, you can set the layer that the label resides on to 0, which will make it behave as if it were a subentity of the parent object. In this case, with the layer set to 0, if the layer of the parent object is frozen, the label will also be frozen (and will no longer be visible).

Table Creation and Label Types In this release of AutoCAD Civil 3D, when creating parcel tables, you can select general line and curve label types and parcel segment labels, including any line or curve labels, that are applied to a line, curve, feature line, or polyline. You can create an alignment segment label that references a general line or curve style for inclusion in a table. General line and curve label styles now have a Tag Mode that supports general line and curve labels, parcel segment labels that reference a general line or curve style, and alignment segment labels that reference a general line or curve style. The Add Table commands (Add Line, Add Curve, and Add Segment) are available on the Lines/Curves menu, the Grading menu (for feature lines), and the Survey Menu (for figures and survey figures). The Renumber Tags command is also available on these menus.


Object Settings Settings in AutoCAD Civil 3D provide many preset values, ranging from values, such as drawing units, scale, and coordinate system, to optional defaults, such as the layers that the different objects are created on, and the use of tooltips. You can access the setting dialog box by right-clicking the appropriate collection on the Toolspace Settings tab, and then clicking Edit Feature Settings. You can work with three levels of settings: ■

Drawing settings establish values for the whole drawing. If you are creating a drawing template, ensure that these are set correctly.

■

Feature settings control behavior for a particular feature, such as Parcels or Grading.

■

Command settings apply to individual commands within a feature, such as the CreateParcelByLayout command within the Parcels feature.

Each lower level object in the settings hierarchy can either inherit or override settings in the level above it. The following illustration shows an override set for area units at the Parcels feature level. The arrow in the Child Override column of the Drawing Settings dialog box (upper drawing) indicates that an override has been set at a lower level. The check mark in the Override column in the Parcel Settings dialog box (lower drawing) indicates that the value set in this dialog box overrides the setting at a higher level. At the drawing level you can cancel an override by clicking it. You can prevent overrides by locking a setting.

Object Settings | 55

Area units for parcel objects are acres, overriding the drawing setting. For other objects, area units remain set to square meters.

How feature settings can override drawing settings


Exercise: Object and Label Styles In this exercise, you create and modify a child label style. Using parcel labels as an example, you will learn how to create a child style and observe how changes to parent styles affect the child styles. To create and change label styles in AutoCAD Civil 3D 1

Open the file C:\Program Files\Autodesk Civil 3D 2009\Getting Started Guide\GSG_styles.dwg. In Toolspace, on the Settings tab, expand the Parcel collection, and then expand the Label Styles collection. Now expand Area and right-click the Standard style. Click New.

2

On the Label Style Composer dialog box Information tab, the new style name is Standard [Child]. Make changes as desired and click OK. Observe that in the Label Style collection, the new child style appears under Standard.

Exercise: Object and Label Styles | 57

This chapter outlines a process for creating drawing templates. You can use drawing templates to save time by establishing a consistent format for drawings and a standard design process.

Creating Templates AutoCAD Civil 3D provides a number of features that contribute to a standard appearance and behavior for all your drawings. These can all be specified in a drawing template, which is saved as a .dwt file. Your organization may need several templates for different customers or project types. Then, whenever you start a new drawing, you can open a template that contains all the required settings and styles. The general process for setting up a template is described in the following sections.

61

STA=22+00.00

Units and precision for alignments are set in the template file.

LOT: 1 Area: 8321.86 sq. m 0.83 hectares

Lot labels are controlled by a parcel label style, which could also be defined in the template file.

Defining standards using a template file and a label style

62 | Chapter 4 Designing Drawing Standards

Drawing Settings As a basis for configuring your drawing settings, choose an existing template that is closest to your needs. To see the available templates, click File menu ➤ New. If you want some preset object styles, the four templates that have names beginning with “_AutoCAD Civil 3D”, are recommended. The names of these templates, such as AutoCAD Civil 3D (Imperial) NCS Base.dwt, indicate some of their settings. The metric or imperial label indicates the main unit of measure. After choosing your initial template, the next step is to review and edit settings. On the Toolspace Settings tab, right-click the drawing name and click Edit Drawing Settings. The Drawing Settings dialog box includes five tabs and many settings.

Use the table on the Object Layers tab to assign objects to layers, and create or rename layers. When designing your use of layers, consider the following points: ■

Objects on the same layer are turned on and off together if you change the layer visibility. For maximum display flexibility, spread objects and their components across several layers.

■

The color of a layer affects all objects assigned to that layer that are drawn in a style that uses the ByLayer color setting. If you set up styles this way, you can change the color of many objects by simply changing the layer color.

Use the Abbreviations tab as a central location in which to set the abbreviations used in object labels, especially for alignment and profile geometry points. Using the Ambient Settings tab requires a careful review, because it provides global default settings, such as the precision of numeric values, and the visibility of tooltips. One very useful setting is the General setting, Save

Drawing Settings | 63

Command Changes To Settings. If you set this to Yes, then whenever you change a setting, such as the radius of an alignment curve, it is saved as the default value for next time. Another important setting on this tab is Independent Layer On. This must be set to No if you want to be able to control object visibility by turning layers on and off. On the Ambient Settings tab, you see a blue arrow in the Child Override column next to any setting that is changed for one or more features (objects) in the drawing. You can cancel the override by clicking the arrow, and you can click the lock icon to lock any setting and prevent overrides at the feature level.

After configuring the ambient settings, you should work down through Point, Surface, and other features in the Settings tree, right-clicking each feature and selecting Edit Feature Settings. Doing this allows you to examine the default styles for each feature and its labels, the feature name format, and other settings that you may want to modify. The ambient settings you configured at the drawing level are available at the feature level in case you want to override them.

Layer Standards Maintaining a standard for the use of layers is easier if you have a drawing template with predefined layers, and styles that reference those layers when objects are created. For additional consistency, save your template as an AutoCAD standards file (.dws format). Then, in the template, enter the STANDARDS command and in the Configure Standards dialog box, link the standards file to the template. If you want to enforce the standards, you can click the Settings button and activate notifications of standards violations, or


override such violations. For more information, see Define Standards in the AutoCAD help.

Object Styles Ideally, your drawing template will have the perfect set of styles for your projects, but this usually takes some time to evolve. To assist the process, create a demonstration drawing that contains one or more surface, alignment, and other object types. Or you can explore the Sample_styles.dwg, that is supplied with AutoCAD Civil 3D. After a default installation, you can find this file at: C:\Program Files\AutoCAD Civil 3D 2009\Best Practices Guide\Sample_styles.dwg. This provides a good laboratory in which to display and develop styles. Consider designing styles to reflect the information requirements at different times in the project. For example, create styles for objects in the design phase, and other styles for their final presentation. Also, you can create styles for different users of the drawings, showing object details and labels that present the data each type of user needs.

Label Styles The styles for labels are another template item that should be developed with a top-down approach, similar to that for drawing settings and feature settings. At the drawing level, click Edit Label Style Defaults. In this context, you can set global standards such as those for text font, size, and label behavior around curves. As with the object styles, after setting label style defaults you can review the feature-level settings and apply any required overrides. In this release of AutoCAD Civil 3D, you can use general line and curve label styles for parcel segment labels, and for alignment line and curve labels. Previously, general line label styles could be used to label only lines, curves, and polylines. The general line label styles are now available from the parcel, alignment, grading, and survey menus. For more information, see Label Objects (page 54). Parcel tables now support general line and curve label types and display either general line and curve labels or parcel segment labels. For more information, see Table Creation and Label Types (page 54).

Object Styles | 65

Plan Production Tools You can use AutoCAD Civil 3D plan production tools to automate the process of creating construction documents from your designs. Select an alignment in your drawing, and using the plan production tools, you can quickly create sheets that automatically display the desired data. You can use the View Frames wizard to create view frames along an alignment. Click General menu ➤ Plan Production Tools ➤ Create View Frames to open the View Frames wizard. After creating the view frames, you can easily create sheets for construction plans. Click General menu ➤ Plan Production Tools ➤ Create Sheets to open the Create Sheets wizard. See Plan Production Tools (page 149) to explore the view frame and sheet creation process. For more information about Plan Production tools, see Plan Production Tools in the Help system.

Enhancing Drawings with Visualization Tools AutoCAD render materials can greatly enhance the appearance of your drawings by simulating real world materials for a more realistic view of the design. Experiment with the render materials to determine which will work best for your drawings. You can use this feature to enhance renderings of surfaces, corridors, and pipe networks. Click View menu ➤ Render ➤ Render to render the object with the selected material. Click View menu ➤ Render ➤ Materials to open the Render Materials dialog box, where you can create new materials and add or remove materials from the current drawing. For more information, see Render Materials in the Help system.


Exercise: Drawing Settings In this exercise, you will open a file that contains alignments and look at some ways to work with drawing settings in AutoCAD Civil 3D. Using alignments as an example, you will learn how to edit the drawing settings to specify the default layer on which new objects will be created. To set up object layers in AutoCAD Civil 3D 1

Open the file C:\Program Files\Autodesk Civil 3D 2009 \Getting Started Guide\GSG_alignments.dwg. Click View menu ➤ Zoom ➤ Window. Draw a rectangle that includes the sketch lines at the bottom. Your view of the drawing should look like this.

Managing Project Data

5

The project management feature of AutoCAD Civil 3D is based on Autodesk Vault, a database for storing and sharing data among members of a project team. This chapter explains how to set up and use Autodesk Vault to manage your projects. The project management system also includes the data reference methods known as External References (xrefs) and Data Shortcuts, which you can use for less complex and smaller projects.

The Collaborative Environment The project management system supports shared access to project files by an entire design team. There are three mechanisms for the sharing of design data within a project: ■

Object references in Autodesk Vault

■

External references

■

Data shortcuts

Before deciding which method to use, consider the complexity of drawings, the number of drawings involved, the size of your project team that will access and edit the files, and your requirements for ease of use as opposed to your need for data security. Each mechanism is best suited to particular project requirements.

Autodesk Vault The heart of the project management system is a set of project folders in an Autodesk Vault database. These folders can contain databases of point objects, along with official copies of surfaces, alignments, and other objects. When you

69

want to edit a particular drawing, you can check it out from the database, which locks it so that other users can get a read-only copy, but cannot edit the drawing. As shown in the following illustration, you can import some read-only reference objects from the Vault database, such as surfaces or alignments into a drawing. These reference objects participate in the design process within your local drawing. You can change their style and labeling, but you cannot change their geometry.

Reference Surface

Parcel Drawing

Reference Alignments

A user with edit permissions for the reference object can check out the drawing that contains the master copy and change it. When the edited version is checked back into the database, any open drawing that contains a reference copy is updated with markers in the Prospector tree and the Windows System Tray, advising the user that the drawing does not include the latest version of the reference object. The user can choose to update the object or not. Whenever a drawing that contains a reference object is opened, it automatically retrieves the latest version of the reference object.

70 | Chapter 5 Managing Project Data

Access to Autodesk Vault When you install AutoCAD Civil 3D, you have the option of installing a stand-alone Autodesk Vault database on your computer. This database is good for experimenting with project management commands, but it cannot support multiple users. The other option is to install the Autodesk Vault server on a network, which creates a multi-user production system. In either case, you can access the Autodesk Vault database on the Toolspace Prospector tab, Master View. Simply right-click the Projects icon and click Log In. Alternatively, on the Windows Start menu, launch the Autodesk Vault application.

Autodesk Vault Set Up If you follow a few general guidelines for creating user accounts and databases, you can ensure that your system balances data security with ease of use.

Database Projects and Folders You can create project directories and folders within either AutoCAD Civil 3D or Autodesk Vault. However, a drawing can contain objects from only one project. In the same project you should include all data and drawings that can possibly relate to each other, to facilitate object sharing. The standard project folder structure for AutoCAD Civil 3D is shown in the following illustration:

Access to Autodesk Vault | 71

In this example, a project named Park Project includes collections of drawings, alignments, and surfaces. Placeholders exist for points, pipe networks, and a survey database. The object collections, such as Alignments, include all objects that are shared within the project, for read-only use by members of the project team. The security framework for project folders is described in the following section.

User Accounts and Roles Each person using your Autodesk Vault database has one of three main user roles: ■

Administrator

■

Vault Editor

■

Vault Consumer

Permissions can be applied to individual users and to user groups. With careful planning, you can minimize the amount of configuration required and create a flexible security system. For example, rather than assigning permissions to each user, you can save time by creating project-specific user groups or


job-based groups, such as Engineers, Project Managers, and Data Technicians. Then, you can add users to the groups and set permissions once for each group. Later, you can move users from one group to another to change their permissions.

Administrator The Administrator role has the highest level of permissions, and is able to do all tasks on the server and within Autodesk Vault databases. Only an administrator can create user accounts, user groups, and databases on the server, and set access permissions. For security purposes, only a few users should have administrator permissions, but enough so that an administrator is always available during work hours.

Vault Editor A Vault Editor has full read-write permissions within Autodesk Vault, and is able to create new projects and folders in the database, add files, and edit files. Assign this user role to anyone who needs to create drawings and share objects within the database.

Vault Consumer A Vault Consumer has read-only access to the database, and is able to get reference versions of objects for use in drawings saved outside of the database. Assign this role to anyone who does not regularly share objects or add drawings to a project.

Autodesk Vault Set Up | 73

External References (xrefs) You can insert into your current drawing an external reference (xref) of the entire contents of another drawing as a display-only object. To insert an xref, click Insert menu ➤ External Reference and in the Select Reference File dialog box, insert a specified drawing (.dwg) into your current drawing. Objects in the referenced drawing cannot be edited, but you can control the display of separate components with the Layer Manager.

Xref Advantages Xrefs may be as simple as a single object or as complex as a complete design. Keep in mind that xrefs insert into your current drawing the entire contents of the drawing. The advantage of xrefs is that they can be used with different DWG types. Xrefs are ideally used when you will not need to manipulate objects within the referenced file. They can also be used with either data shortcuts or Autodesk Vault. Another advantage of using xrefs is that you can label them in your current drawing. Because parcel data is not supported by Vault, you can import parcel xrefs and then can annotate them as you would any other object. You can also create parcel tables using xrefs. It is recommended that you do not label xref data in the source drawing, but rather in the current drawing. NOTE Any changes to the source drawing will be reflected in the current drawing’s xref labels.

Xref Constraints Xrefs are display-only and they provide no access to object data such as surface elevations or alignment length. For example, you cannot create a surface profile from a surface in an xref. Both data shortcuts and Vault object references provide access to object data. Xrefs are best used when you do not need to edit objects within the referenced file. Links can be easily moved and reference files renamed with ease. Use caution as xrefs do not provide the security mechanism that Autodesk Vault does.


Data Shortcuts You can use a data shortcut to import a complete reference copy of an object into one or more drawings. Data shortcuts offer great flexibility, and you can easily learn to use them. The data shortcut method is ideal for use by small design teams in which all members have access to a shared network location. In this release of AutoCAD Civil 3D, there is a new Data Shortcut Editor that facilitates this process. Use this editor to create data shortcuts and folders in which to store the reference copies.

Data Shortcut Advantages Data shortcuts are a convenient way to share object data that is entirely based on drawings without the complication of maintaining a database. These objects automatically update when you open a file in which you have referenced data. Reference objects are data shortcuts that can have styles and labels that are different from the source drawing. Data shortcuts can be used to reference surface, alignment, profile, pipe network, and view frame group objects. An example of a data shortcut would be to reference an alignment into a drawing in which you want to create profiles. You can use the data shortcut to keep profiles in a separate drawing from the alignment, to abide by the best practice of “one object per drawing.” For more information about data shortcuts, see Using Data Shortcuts in the Help system. For Data Shortcut Editor information, see Data Shortcut Editor Help.

Data Shortcut Constraints Data shortcuts do not provide data versioning or security controls. They should be used only when team members have equal access to project files.


Exercise: Creating a Data Shortcut In this exercise, you will learn how to create a data shortcut by referencing data from another drawing. You will reference surface object data into a parcel design drawing and create a data shortcut from the Data Shortcuts node on the Toolspace Prospector tab. This exercise also demonstrates how to access the new Data Shortcuts Editor and use it to create the reference. To create a data shortcut in AutoCAD Civil 3D 1

Open the file C:\Program Files\Autodesk Civil 3D 2009\Getting Started Guide\GSG_alignments.dwg. Keep the drawing open, but minimize it for now. Open the file C:\Program Files\Autodesk Civil 3D 2009\Getting Started Guide\GSG_parcels.dwg. In Toolspace, on the Prospector tab, in Master View, right-click Data Shortcuts and click New Data Shortcuts Folder. In the New Data Shortcut Folder dialog box, specify the name as Data Shortcut Test. Click OK.

This chapter explains and illustrates the concepts underlying AutoCAD Civil 3D features. Each feature section in this chapter has a corresponding drawing file. Each drawing illustrates the concepts introduced in that section. You can open the file to see examples of the objects and their various components. There is also a corresponding exercise for each feature, which gives you some basic hands-on experience with AutoCAD Civil 3D. The drawings also provide a good “sandbox” environment in which to explore product features and settings beyond the exercises.

Points The central repository for point information is the project database. The database is typically located on a central server and shared by a number of users, who attach the database to their drawings. However, point presentation is handled in the drawing. Point groups reference the point data directly and are responsible for drawing the points. Point groups have an override that forces all points in the group to use both that group’s preferred point style and point-label style, rather than the styles assigned to the individual points. You can insert or import points from different sources and in different formats. For example, you can define sets of description keys to help organize the insertion of points. Description keys use the raw description of incoming points to control the creation of each drawing point, including the following actions: ■

Assigning the point to a specific layer

■

Assigning a point style

■

Assigning a point label style

■

Translating the raw description into a full description

■

Rotating or scaling the point symbol

81

Points can also be created directly in the drawing, using a wide variety of methods, which are all available from the Points menu.

Points: Getting Started Exercise | 85

Surfaces You can work with two types of surfaces: TIN (triangulated irregular network) and grid. For each of these types, you can create volume surfaces, which are differential surfaces created from two existing surfaces. Surface styles define the appearance of any surface. They can also be used to control the visibility of any analysis that has been performed on that surface. Watersheds can be drawn on the surface, with information about the type of drainage area and where each area drains to. Boundaries define the visible area of a surface. Only the area within the boundary is included in calculations, such as for total area and volume. You can also define masks to hide or show parts of a surface for editing or presentation purposes, while still including that area in calculations. Breaklines are used on TIN surfaces to define linear features that triangles cannot cross, such as retaining walls or streams. Breaklines affect triangulation of the surface. You can define different sets of contours, for example, for different intervals. Smoothing is provided for the surface object as a whole, which gives better results than simply smoothing the contours. In AutoCAD Civil 3D, the build process for surfaces is incremental. Whenever data is added or corrected, the surface is updated. Each surface has a definition list. This list contains all the operations performed on the surface. By turning the operations on and off, you can return a surface to a previous state or modify it to support different types of analysis.

Surfaces Drawing Open the file: C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_surfaces.dwg. The drawing contains two named views. To go to a named view: 1 Click View menu ➤ Named Views. 2 In the View dialog box, click the view you want. Click Set Current. Click OK.

Surfaces: Getting Started Exercise | 89

Grading You create a grading by selecting a base line in the drawing, and then specifying a projection method and target, for example, grade at 3:1 to meet an existing surface. Save time and effort by predefining such values and saving them as grading criteria. Subsequent gradings you create will use the current criteria. You can also create named grading styles that combine specific display properties, such as colors. In addition to using the current criteria, any grading you create uses the current style. A grading normally consists of a face bounded by a base line, a target line, and several projection lines. The base line can be any open or closed figure from which you want to project the grading. It can be a feature line or a lot line. A feature line is any linear feature in the drawing, such as a ridge line, building footprint, or the bottom of a swale. The target for the grading can be a surface, a distance, or an elevation (absolute or relative). Each site can include grading groups, which bundle individual gradings into named sets. Before creating a grading, you must create a new grading group, or select one that already exists. A surface can be created from a grading group, and a grading group can be pasted into a surface. The surface will then be updated if you change the grading. After you create a grading group, volume tools within AutoCAD Civil 3D show you the amount of cut and fill required for the grading design. You can raise or lower the grading group incrementally to adjust volume requirements. You can also change the elevation of points along a grading base line, change the grade of a base line, or modify the grading criteria.

You can click in the elevation cell for any row in the table and change the elevation. The related grades change automatically.

Grading: Getting Started Exercise | 93

Parcels AutoCAD Civil 3D provides a site topology that includes intelligent parcel objects. Each parcel is an independent object that usually represents real estate parcels or lots. You can also import parcels as simple polylines and then convert them to parcel objects. Parcels consist of a series of segments that can be edited individually. Editing parcel segments dynamically updates the parcel properties. Deleting a segment can result in one parcel merging with another. Each site contains one collection of parcels. The hierarchy of parent site and child parcels is managed on the Prospector tab in Toolspace. The parent site represents the original area to be subdivided. By creating a number of separate sites, you can manage large projects with many lots grouped in separate blocks. You can create parcels one at a time or as a group, with settings for the default area and minimum frontage of each parcel. Parcel layout tools give you precise control over parcel area and the angle of each lot line. Parcel styles determine the appearance of the parcel, including fill patterns for the area and linetypes for the segments. There are separate label styles for parcel areas and parcel segments.

Parcels Drawing Open the file: C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_parcels.dwg. The drawing contains two named views, as shown on the following page.

Open the Create Parcels - Layout dialog box as you did in Step 1 and Step 2. Note that the default Parcel Style is now Parent Parcel.


Alignments Horizontal alignments are used to represent roads and other linear objects that follow a path in space. Alignments can include lines, curves, and spirals, which can be joined by constraints. When you edit an alignment, for example, by dragging a grip, the components of the alignment can maintain tangency to one another. You can create alignments from existing polylines, or by using alignment layout tools in AutoCAD Civil 3D. You can edit an alignment either by grip editing or by using the edit commands. Some of the creation and editing options are as follows: ■

Draw a series of tangents, then add curves or spiral-curve or spiral-line groups at the PIs (Points of Intersection).

■

Draw single lines, curves, and spirals.

■

View and edit the dimensions of alignment components.

■

Apply superelevation to the curves along an alignment.

Use station equations to change station-distance references at any point without physically changing the geometry of the alignment.

Now you will create a curve between two connected lines. Click Lines/Curves menu ➤ Create Curves ➤ Curve Between Two Lines. At the bottom of the drawing, select a horizontal line as the first tangent and then select the connected vertical line. Now you are prompted with multiple options with which to determine the size of the arc. Select length (L) and enter 111. The drawing appears as shown here. For further exploration, try using the various methods of determining the size of lines and arcs.


10

Now you will convert the newly created arc entity to an alignment. Click Alignments menu ➤ Create Alignment By Layout. In the Alignment Layout Tools, click Convert AutoCAD Line and Arc. You are prompted to select an arc or line to convert. Select the arc and observe that it is now defined as an alignment.


Profiles Profiles (also known as vertical alignments), are derived from horizontal alignments in the drawing. There are two types of profiles. Surface profiles, often called existing ground (EG) profiles, are extracted from a surface. Layout profiles, often called finished grade (FG) profiles, represent a designed surface such as a road. A profile can be dynamic, in which case it is linked to a surface to reflect updates to the surface or the horizontal alignment. It can also be static, to preserve a record of a surface at a particular time. You can use three types of vertical curves in a profile: parabolic, asymmetric parabolic, and circular. You create static profiles in various ways, such as importing a text file, importing an XML file, or by using the Profile Layout Tools dialog box. Edit a profile by grip editing or by using the edit commands in the Profile Layout Tools dialog box. Profiles are displayed in graphs called profile views. Profile views are separate objects that have their own sets of styles. You can add data bands to annotate the profile view with stations and elevations, horizontal geometry points, or other useful data. You can save several data bands in a set that can be easily applied to other profile views.

Profiles Drawing Open the file: C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_profiles.dwg. The drawing contains two named views, as shown on the following page.

In the drawing, click the alignment so that the blue grips appear, as shown in the illustration. Drag the grips to modify the alignment dynamically. As you modify the alignment, the profile will update at the same time.

5

The green profile in the profile view at the top of the drawing represents the intersection of the alignment with the existing ground surface. The profile looks like this before you modify the alignment.

6

Click the square grip at the far left of the alignment. (Try to watch the green profile as you complete the following step.) The grip turns red to show that it is active. Drag it a little farther to the left and then release it.

7

Note that the profile has been extended to include the addition to the alignment. It now looks something like this. (You may want to experiment further and see the effect of editing the alignment curves before you close this drawing.)

Profiles: Getting Started Exercise | 109

Sections Sections, or cross sections, are cut across a linear feature to a specified distance on the left and right of a center line. Sections are typically sampled at given stations along a horizontal road alignment. Edits to an alignment update the sections as well. Sections are located on sample lines that cut across the alignment. Sample lines have their own styles and can be labeled. A set of sample lines makes up a named collection called a sample-line group. Sections are displayed in a graph called a section view. A section view is very similar to a profile view. It consists of a grid or graph with attributes that are controlled by section-view styles. You can also display data bands above or below the section view. You can plot individual sections for a specific sample line, or all the sections for a group of sample lines. To plot multiple sections, use a paperspace viewport to set up the sheet. Sections, like alignments and profiles, support label sets. Label sets enable you to save and apply an unlimited number of different types of labels.

Mass Haul Diagrams: Getting Started Exercise In this exercise, you will open a file that contains sections and explore the process of creating mass haul diagrams in AutoCAD Civil 3D. Use mass haul diagrams to graphically display a partial or overall view of earthwork volumes. They are used to analyze aspects of the design, such as the distance over which cut and fill will balance, the amount of material to be moved, and the direction of movement. To generate a mass haul diagram, your drawing must contain an alignment, a sample line group, and a list of materials. Any corridor from which you generate a mass haul diagram will have a baseline alignment, and many will have one or more sample line groups. You will also explore the use of the Mass Haul Diagram Creation wizard and learn how to edit a mass haul line style. To create mass haul diagrams in AutoCAD Civil 3D 1

Open the file C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_sections.dwg. Click Sections menu ➤ Compute Materials. In the Select A Sample Line Group dialog box, Basic Road is the assigned alignment. The sample line group is SLG-1. Note that a sample line group must be selected to create mass haul diagrams. Click OK.

In the Select Style dialog box, change the color to red. Click Apply. Click OK. The mass haul line displays as red in the drawing.

Pipe Networks You can use the pipe networks feature to design and model networks that support the flow and function of a utility system, such as a storm or sanitary sewer. You build a model of a pipe network using individual parts, much like a real-world pipe network, connecting pipes in your network either with or without using structures, such as manholes or catch basins, and adding inlet or outlet structures, such as headwalls, to mark the terminating end of a pipe run. After you have created your initial network design, you can view and edit network parts in virtually unlimited ways within plan view or in a profile view. You can also view the pipe network parts in a section. Preset design rules control the slope of pipes, their depth relative to a surface, and the sizing of the structures that connect the pipes. This is useful when you are designing a gravity system, such as a storm or sanitary sewer.

Pipe Networks Drawing Open the file C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_pipe_networks.dwg. The drawing file contains three viewports: the pipe network in plan view, the profile view of some of the network pipes and structures, and the same parts in a section view.

Pipe Networks | 117

The left pane shows a pipe network segment made up of two manhole structures connected by pipes. The network parts have been placed at a specified offset from an alignment, and are drawn in a profile view created using the same alignment (upper-right pane). A sample line placed at station 7+71 was used to create a section view (lower-right pane) that shows a cross-section view of the pipe network parts located at the station. You can edit the positions of the pipe network parts manually by using editing grips in either plan, profile, or section view, or by directly editing their properties.

Click the structure to connect the pipe end to it. Pan to the structure that is offset from station 1+00 on East-West Drive. With the connection marker active, click the structure to connect the pipe to it. Press Esc to end the command.

Pipe Networks: Getting Started Exercise | 121

Corridors Corridors are used for roads and similar structures that follow a designed route across the terrain. A corridor is a detailed three-dimensional design that combines data from a horizontal alignment, a profile view, and an assembly. The corridor can automatically reflect changes to any of the parent data. Subassembly objects such as road lanes, curbs, and shoulders form the building blocks for an assembly. When you apply the assembly to an alignment and a profile, a corridor is generated in three dimensions. At each point along its linear path, the corridor adapts to conditions, such as superelevation and cut or fill requirements.

Corridors Drawing Open the file C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_corridors.dwg. The drawing contains three viewports. Although the corridor, profile view, and assembly are all within the same drawing, the viewports help you see the object relationships. In the left pane, the horizontal alignment starts at the top of the corridor and runs to station 1658 at the bottom. In the profile view, station 0 is on the left side, and green vertical lines across the grid show the start and end points of the horizontal curves. In the assembly view, you can see that the corridor assembly includes two road lanes, a curb on the left, a sidewalk on the right, and side slopes on each side. The side slope subassembly (BasicSideSlopeCutDitch) is designed to create a ditch only on cut slopes, and the ditches are visible along the corridor. You can use the Object Viewer to see the corridor in a three-dimensional view that shows the cut and fill regions. Click the corridor, then right-click and click Object Viewer. Click near the bottom of the Object Viewer window, then click and move the cursor up to tilt the corridor. If you want to pan or zoom the display, right-click inside the Object Viewer window.

Object and Label Styles The object styles in AutoCAD Civil 3D have general attributes, such as object color, visibility of components, linetypes, and fill patterns. Similarly, label styles work with text format, data content, location, and graphic elements, such as leader lines and bounding boxes. Within your design process, object and label styles should be created with specific purposes in mind, such as representing objects at different approval stages, or displaying the right information for different types of users. Before you create object styles, it makes sense to experiment with editing styles for different objects and to learn the available controls. Style components vary according to object type, but most object and label styles are accessible in the same two ways: ■

In Toolspace, on the Prospector tab, right-click an object and click Properties to see the object style. Some objects also show the label style here. Click the list button next to the style name and select Edit Current Selection to review or edit the style components.

■

In Toolspace, on the Settings tab, expand the object collection to see all the styles for that object, organized by types. Right-click any style name and click Edit to review or edit the style components.

For objects, you can access labels from the main object menu either by clicking Add Label or by using the Annotation menu (available when the Annotation and Drafting workspace is selected). You can create sets of labels for alignments, profiles, and sections in order to manage multiple labels easily. After the set is defined, it can be applied to or removed from an object in a single operation. The Getting Started exercises for object styles and label styles make use of the same drawing.

The style change is displayed in the drawing.

Label Styles: Getting Started Exercise | 137

Visualization You can use the visualization tools in AutoCAD Civil 3D to create enhanced design drawings using model rendering materials that correspond to specific real world materials in a design. AutoCAD render materials simulate the characteristics of materials such as asphalt, concrete, and gravel. To visualize a material with a render material, the material must be included in the current drawing. You can easily add materials to a drawing from the tool palette or by dragging materials used in one drawing into another drawing. You can also create a new render material, and save it to use as part of a drawing template or copy it into other drawings. In AutoCAD Civil 3D, you can apply render materials to features, such as surfaces and surface masks, corridor surfaces and corridor surface boundaries, and pipes and structures.

Label Objects You manage label objects in AutoCAD Civil 3D with standard AutoCAD commands as well as Civil 3D commands. You can use the AutoCAD Properties palette to edit multiple labels in a single operation. For example, you can use the Properties palette to access the Text Component Editor in order to simultaneously edit text content for a group of any number of labels. If you are editing a drawing that includes dozens of pipe network parts with corresponding labels, you can edit the text, change the appearance, or reset the location of all of the labels at the same time by using multiple selection. It is important to remember that you can also select subentities of group type labels with the Ctrl-click selection method in order to edit individual labels one at a time. As independent objects, label objects are not “subentities” of a parent object. They reside on their own layer, the default of which is controlled using drawing settings. The Getting Started exercises for label objects makes use of the same drawing as profiles.

Managing Label Objects: Getting Started Exercise You can use the label objects in AutoCAD Civil 3D to manage multiple labels by editing one or more properties with the AutoCAD Properties palette. The label objects are versatile. You can select individual label subentities using Ctrl-click in order to edit single labels that belong to the group. Label objects are controlled using standard AutoCAD commands in the Properties palette. You can control properties such as color, layer, linetype, and lineweight in addition to the label style and placement options. In this exercise, you will explore how to manage labels with the AutoCAD Properties palette. Using profile labels as an example, you will learn how to edit a group of label objects and also how to select and edit a single label object. You will also explore how to use grips to manage label placement. To manage labels 1

Open the file C:\Program Files\AutoCAD Civil 3D 2009\Getting Started Guide\GSG_profiles.dwg. Click View menu ➤ Zoom ➤ Window. Draw a rectangle in the top center to zoom your view of the drawing so that Profile View: East-West Drive displays at the top as it does in this illustration. On the profile, double-click one of the EG labels. The group of labels is highlighted with square grips as shown here. Note that the label group style is Standard and the labels are blue. The Properties palette is also displayed.


2

In the Properties palette, under Labeling, click Profile Grade Break Label Style and change the setting from Standard to Grade Over Elevation. Note that the entire label group has now changed to the Grade Over Elevation style. The result is shown in the illustration. Note that you can access the Select Style dialog box by selecting Create/Edit. From this dialog box, you can open the Label Style Composer by selecting Edit Current Selection.

3

Now you will select a subentity of the label group and change its style. Zoom out of the drawing so that you can see several components of the label group. Use CTRL-click to select one of the labels. Note that only this label is highlighted (with the blue square grip) as shown in the illustration and the Properties palette is displayed.

Change the Label Style setting to Standard and note that the label style reverts back to Standard. The label is now blue. The result is shown in the illustration.

5

Now you will learn how to reset label location. Click the label you selected in Step 3. The grip color is now red, indicating that it can be moved. Drag the label with the square grip and move the cursor away from the grip. The square grip is blue and another round blue grip is visible alongside the square grip. This round grip is a reset grip which can be clicked to restore the label to its original location. Click the round grip. You can make multiple drag edits to the label and the reset grip will reset the label to its original location. If you move a number of group labels, right-click a label and select Reset All Group Labels.


Plan Production Tools Use the Create View Frames and Create Sheets wizards to create sheets that automatically display segments of alignments and profiles in your plans. You can create view frame groups that automatically capture predefined areas along an alignment. Instead of needing to manually create many viewports on layouts to show segments of alignments, you can create view frames that automatically capture predefined areas along an alignment. View frames are rectangular areas along an alignment that represent what is displayed in the associated viewports on the layouts (sheets) to be created. This automation saves you from making many manual changes when your design data changes. The plan production tools simplify the process of preparing sheets from your design drawings. After you select an alignment in your drawing, in just a few seconds you can create sheets that automatically display the desired data. For information about Sheet Set Manager or the plotting or publishing processes, see the AutoCAD Help. For information about Plan Production tools, see Plan Production Tools in the Help system.

2D polyline A polyline with all vertices at the same elevation. 3D face An AutoCAD object that represents the surface of a 3- or 4-sided area, with each vertex potentially at a different elevation. You can view TINs (Triangulated Irregular Networks) as 3D faces. Using the SHADE command, you can shade 3D faces. Using the RENDER command, you can render the 3D faces. See also TIN surface. 3D polyline A polyline with vertices at varying elevations. A.A.S.H.T.O. American Association of State, Highway, and Transportation Officials. acre A measure of land: 160 square rods; 4,840 square yards; 43,560 square feet. alignment A series of 2D coordinates (northings and eastings), connected by lines or curves, used to represent features such as the road centerlines, edges of pavement, sidewalks, or rights-of-way. angle The difference in direction between two convergent lines measured in the units of degrees, radians, or grads. area The quantity of plane space in a horizontal plane enclosed by the boundary of any polygonal figure. assembly The combination of one or more subassemblies forming a typical section. The assembly is applied along a horizontal/vertical alignment to form a singular path-like structure. azimuth A clockwise angle measured from a reference meridian. Also known as north azimuth. It can range from 0 to 360 degrees. A negative azimuth is converted to a clockwise value. base line The object to which grading criteria are applied. A base line can be an open or closed 2D or 3D geometric figure that is a feature line or a lot line. See also control region, feature line.

Glossary | 153

base surface An existing ground or undeveloped terrain. Specified when creating volume surfaces. See also comparison surface, volume surface. bearing An angle measured from North or South, whichever is nearest, with the added designation of East or West. The angle is always less than 90 degrees (PI/2 radians or 100 grads) and is usually referenced by a quadrant number. border (surface) The visible limits of a surface. The border may or may not be defined from a boundary or may be the result of a defined boundary and operations performed on a surface, such as a Delete Line operation (a hole is created in the surface). If a boundary is not defined on a surface, the exterior border is always defined as the extents of the surface triangulation. boundary (surface) One of three kinds of closed polylines that limit the display area of the digital terrain model. Most common are outer surface boundaries constructed just outside the extremities of the dataset, eliminating unwanted interpolations across empty space where the surface has a concave shape. Also used are two types of internal surface boundaries: hide boundaries, to punch holes in a surface, (for example, a building footprint), or show boundaries, to create smaller surfaces by eliminating areas that fall outside the boundary. bounded volumes A method of calculating volumes using an existing AutoCAD object (for example, a polyline or polygon) to calculate the cut, fill, and net volume for the area bounded by the object. breakline A line used to connect the data representing a distinct surface feature, like a ridge line, edge of pavement, toe of a slope, centerline of a road, or flowline of a ditch or stream. When a breakline is defined, the surface triangulation must first follow the breaklines, by placing triangle edges coincident with the breakline segments. This ensures the feature in the model is accurately depicted. Then, the rest of the interpolation is performed based on proximity. Breaklines are typically critical to creating an accurate surface model. It is the interpolation of the data, not just the data itself, that determines the shape of the model. See also non-destructive breakline. breakline point A point that is included in the list of vertices for a defined breakline. ByBlock A setting specifying that a component of an object inherits the color or linetype associated with the object, or block, that contains it. ByLayer A setting specifying that an object or component of an object inherits the color or linetype associated with the assigned layer. catchment area The area tributary to a lake, stream, or drainage system.

CS See curve to spiral. curve to spiral A point on a horizontal alignment where a curve meets a spiral. cut slope The slope created when the base line falls below the existing ground line. The resulting slope matching up into the existing ground is called a cut slope because the existing ground must be cut (removed) during construction. data band A graphic frame that is associated with a profile view object or section view object. The data band contains annotations for the profile or section view, as well as for the parent horizontal alignment. Some common annotations include elevation data, stations, and cut/fill depths. data collector A device surveyors use to automatically record the observation data they collect in the field. The raw survey data is downloaded and converted into a field book file, which is written in the Survey Command Language format, or a LandXML file, which uses the LandXML schema to describe the Survey data. Surveyors can then import this file to create points in the database and figures in the drawing. datum A reference value. All elevations or coordinates are set relative to this value. In surveying, two datums (horizontal and vertical) are generally used. For global coordinate systems, a datum refers to the ellipsoid information and the techniques used to determine positions on the Earth’s surface. An ellipsoid is part of a datum definition. daylight line A line showing the line of zero cut or fill within the job area. Daylight lines are also known as match lines. decimal degree The measure of an angle in decimal units. For example, 3°30'36" equals 3.51 decimal degrees. definition list A list that contains all the operations performed on a surface.

Examples of subassemblies include lanes, curbs, and shoulders. subdivision An unimproved tract of land surveyed and divided into parcels for purposes of sales. surface A network of elevation data (either TIN or Grid). The points of a surface are connected into either triangles or a grid, which are then used to interpolate contours, and to generate profiles and cross-sections. A surface represents the ground condition at a particular time or event. surface border See border (surface). surface boundary See boundary (surface). surface distance The distance between two points, measured along the ground surface. On a sloped surface, the distance between two points can also be measured as a horizontal distance and a vertical distance. surface profile A profile object that represents existing ground elevations along a horizontal alignment or other linear feature that supports profile views. Typically, this data is derived from an existing surface or data file, and consists of a series of connected vertical tangent lines without vertical curves defined. Vertical curves can be added if required. surface smoothing A process that interpolates and extrapolates surface data to derive additional elevation values. Kriging and Natural Neighbor Interpolation (NNI) are the two methods of surface smoothing. Survey tab The tab in Toolspace where you access and manage survey settings, survey-related databases, and survey project data. tangent A straight line segment that forms part of a horizontal alignment or profile. Tangent distances are measured as the horizontal distance between the two end points.

target The element of grading design criteria that determines what the grading is going to intercept. A target can be a surface, absolute elevation, relative elevation, or distance. target line In a grading, the target line is either the resulting geometry created by applying grading criteria to a base line, or a lot line that was selected as the target. See also grading face, grading target. template A collection of default settings and styles used to create a drawing. terminators Graphics, such as arrowheads, ticks, or crow’s feet, that are displayed at the end of lines, arcs, or spirals. tick A component of a label that is usually a mark (or short line) inserted in a series at perpendicular angles to another object, such as a line or curve. TIN surface Triangular Irregular Network. A TIN is the most common method of interpolating elevation data. The points are connected into triangles that are used to interpolate for contours, and to generate profiles and cross-sections. The lines that make up the surface triangulation are called TIN lines. See also 3D face. TIN volume surface A differential surface created from a composite of points based on base and comparison surface. Also known as a differential surface. Toolspace A window that provides an object-oriented view of your engineering projects. Toolspace is divided into four parts or tabs: Prospector tab, Settings tab, Survey tab, and Toolbox tab. topography The features of the actual surface of the Earth. topology A set of geometric connections between objects. Objects linked by topology maintain their relationships with one another. In AutoCAD Civil 3D, objects that share the same topology are grouped together in a site. See also site. transition region An area of a grading that blends the control regions on either side of the grading. A transition region has no design criteria assigned to it. transparent command A command that can be run while another command is in progress. Transparent commands begin with an apostrophe (‘). triangle area The 2-dimensional (2D) area of a triangle face computed from the northing and easting of each triangle point. The total triangle area is the sum of all 2D triangle areas with the surface boundary(s).

trim (surface) The process of removing unwanted TIN lines from a surface, thereby removing triangles. vault A database managed by Autodesk Vault. vertical alignment See profile. vertical curve A curve used on a profile (most commonly on layout profiles) to provide a gradual change in slope from one tangent to the other. There are three types of vertical curve: parabolic, circular, and asymmetrical. vertical exaggeration An increase of vertical scale relative to horizontal scale, used to make grade changes easier to differentiate. See also vertical scale. vertical scale The scale that is compared to the horizontal scale to calculate the vertical exaggeration in profiles and cross sections. It does not actually change the scale that is used when the drawing is plotted. See also vertical exaggeration. void region An area along a base line where grading has not been applied, creating a gap in the grading. volume surface A surface that is created by calculating volumes using the grid (differential) or TIN (composite) methods. The surface is created from the two surfaces that make up the stratum. The elevation values of a volume surface are actually the difference between the two surfaces. For example, at point 1000,1000, the bottom surface has an elevation of 100, and the top surface has an elevation of 150. The elevation of point 1000,1000 on the volume surface is the difference between the two surfaces, which is 50. wall breakline A breakline that represents surface features, such as retaining walls, curbs, bridge abutments, and so on. watershed The catchment area for rainfall that is delineated as the drainage area producing runoff. Base flow in a stream also usually comes from the same area. weeding The removal of points along a selected polyline representing a contour. The weeding factors determine the amount of points removed. You can use weeding to reduce the amount of point information taken from the contours that may not be necessary to generate an accurate surface. See also weeding factors. weeding factors The settings used to reduce redundant points along the contours by ignoring contour vertices that are close together or along a straight line. A larger distance and deflection angle will weed a greater number of points. See also weeding.
