The Part Filter option allows you to display or hide parts of an object or faces which have been assigned to sets in the modeling environment, or parts which make up an assembly. One or more of these sets or parts can be selected to be hidden or displayed in the drafting view.
In the following example, the sub-assembly Fixed Side (static Mold Parts) has been unselected and will be hidden from the view.
Create a view then proceed as follows:
Click the Part
filter button
in the View
creation dialog.
Click Assembly tree and check the sub-assemblies and/or their parts to include/exclude them from the view (The sub-assemblies and/or their parts are highlighted in the view as they are checked). (The sub-assemblies appear in the Part Filter hierarchically like they do in the Cimatron E Explorer).
OR
Click on the geometry in the view then from the popup menu, double-click the sub-assembly or part to be hidden. The Assembly Tree is updated accordingly (unchecked).

If required, check the Show hidden entities option to display entities hidden in sets in the part document
Click OK. and exit. The selected sub-assemblies are hidden/displayed in the view accordingly:

In the following example, the upper and lower clamping plates have been assigned to a set and will be hidden from the view.
Click the Part
filter button
in the View
creation dialog.
Click the Sets option and mark the check box in the Part Filter dialog of the parts to be displayed. Hold down the CTRL key in order to select more than one set or the SHIFT key to select the first and last sets of a row. . The Unassigned Assembly Set contains all left over geometry, i.e. geometry not assigned to any set.

Click OK. and exit. The selected sets are hidden/displayed in the view:
Notes:
When working with an assembly, only components can be selected for inclusion in a set.
Selecting/unselecting a sub-assembly automatically includes all its components.
If the model does not contain sets, the option is disabled
When working with an assembly, hidden sets of the part are hidden in the assembly and in the view.
The default settings of the assembly attributes (whether hidden or shown) are defined in the Cimatron E Explorer.
When the Part filter dialog is opened for a new view, the status of the sets (hidden, displayed) is according to the status in the model.
When selecting an existing view (to create a new projection or derived projection), or a section view, the part filter list is copied to the new view with its current default status.
When selecting a detailed view, the part filter option is disabled. The displayed & hidden entities will be the same as the base view.
Updating the model part automatically updates the set entity list and the view is updated accordingly.
