Select OK. Load Work The main assembly file is loaded. Note the assembly structure. The parting assembly will later include the workparts and parting face parts. This helps organize the spilt work. A mold assembly has been created. There is a structure of fixed side, moveable side, parting, and ejection sub-assemblies.
Note that the layout part holds a coordinate system for every cavity location. In this instance there are two cavity locations. The outer box represents an optional mold base size. This box is a simple sketch that represents a preliminary mold base size. It can be edited to any size to help with the layout until a mold base is built.

Parting Surface Part Main Parting Surface Part (PSP) We'll now add the parting surface parts. This mold is composed of a cavity plate as an active part in the fixed side, and an insert (composed of the model and a mirror model) in the movable side. In multi-cavities it is recommended to create two types of parting surface parts: Main: The parting surface that usually holds the outer boundary of all instances. This parting surface part will be placed on the main assembly UCS of the parting assembly. Local: The parting surface that is common to all or some of the instances (or their mirror parts). This parting surface part will be placed on the UCS of one of the instances. Show only the parting assembly and layout part for a clearer display. From the guide, select the Parting Surface Part option.
Name the parting surface part: Main.

Select Adjacent Planar and Cone faces. Select them by box as indicated by the arrow in the picture below and exit.
All the free edges of the selected faces are highlighted.
You are now requested to select a reference closed sketch. Enter the sketcher on the XY plane. Create the following sketch. Show the layout part to ensure that the sketch exceeds the boundaries of the mold.

Upper/Lower Delta Exit the sketcher and view the preview of this feature.
The faces are extended towards an imaginary sweep face created by the sketch. Change the Upper/Lower Delta value to 0 and select OK.
Note that the internal parting faces were also created. The Upper/Lower Delta value controls the cupping plane or face of the upper and lower bounding boxes of the selected faces.
More information regarding Upper/Lower Delta value: In our example it is obvious that the extension of the vertical face will never reach the imaginary sweep faces. Although it is the required result in our case, in other cases we would sometimes prefer to extend these faces.
30
CimatronE 9.0
Basic Xelerate Mold Project Tutorial
Therefore we'll use the Upper/Lower Delta value. The system internally creates a bounding box of the part using the UCS defined by the sketcher plane. The system then creates imaginary sweep faces that run from the lower plane (parallel to the lower box boundary with the defined delta) to the upper plane (parallel to the upper box boundary with the defined delta). The imaginary sweep faces define where the extension will be stopped. See example below with upper/lower delta = 10:
