Managing Part-CAD Document Relationships
You can drive and update Windchill part structures when you check CAD documents into Windchill. This is referred to as “CAD driven” (bottom-up) design. It is also possible to drive and update a CAD structure from a Windchill part structure. This is referred to TDD (top-down design).
