About Intersected Components
When you create an assembly feature that removes material, it intersects at least one assembly component. The intersecting feature is visible in the Model Tree as an assembly feature and as a feature of each of the intersected components. When an intersected component is part of a family table, you can set other family table members to be intersected as well. You can then use them to replace the original component in the assembly while maintaining the feature.
Intersected component instances are invisible in Family Tables, the BOM, and in Integrate Difference tables when you use the system-generated names. They are, however, visible in Family Tables, the BOM, and Integrate Difference tables when you give them a specific name.
Both the original model and the new, intersected model are in memory while the assembly feature is present.
When you set the advance_intersection configuration option to yes or select the Advanced Intersection check box, you can configure the following advanced options:
Define the display level separately for each component.
Determine Family Table instances intersected by the feature.
Use the Intersection tab in the feature tab to define or edit the definition of the intersect feature. Use the Intersected Components dialog box to edit component instance assignments.
