Managing Deleted Occurrences in a CAD-driven Part Structure
Child parts that have been removed, disappear from the part structure. However, the system keeps track of deleted part occurrences and their relationship to CAD document structures. You can modify the build status of a deleted part occurrence, before or after the build has occurred, using Manage Deleted Occurrences. You use this action to see what occurrences have been deleted and to decide how deleted occurrences impact future build operations.
To change the build status of deleted part occurrences:
1. In the Structure tab, select the assembly part within the Structure pane that has the deleted part occurrence.
2. From the right-click actions menu, select CAD > Manage Deleted Occurrences.
The Deleted CAD Synchronized Occurrences window opens showing all part occurrences in the assembly part that have been deleted.
3. Check the Remove from CAD Assembly column and note the build status of the deleted occurrences.
4. Toggle the build status of the deleted part occurrences between Excluded and To Be Built using the drop-down menu in the Remove from CAD Assembly column of each part occurrence row.
* 
Excluded – This status causes the deleted occurrence to be ignored when a build operation is performed. The deleted part occurrence does not cause the related CAD model occurrence to be deleted from the CAD model structure.
To Be Built – This status causes the related CAD model occurrence to be deleted from the CAD model structure.
5. Click Close to commit your changes.
The changes in build status are reflected in the CAD document structure the next time a build operation is performed.
Undeleting a Deleted Occurrence
You must remove an occurrence from the Deleted CAD Synchronized Occurrences window and rebuild the CAD model structure from the part structure in order to include the previously deleted occurrence in both structures.
To remove a deleted occurrence:
1. Select an occurrence in the Deleted CAD Synchronized Occurrences window.
2. Click the remove icon at the top of the table.
The deleted occurrence is removed and re-included it in both structures.
