Comparing CAD and Part Association Types
The following table lists the association types that you can establish between CAD documents and Windchill parts with a summary of their characteristics.

Many CAD documents can be associated to the same Windchill part. However, a single CAD document cannot be associated to multiple Windchill parts using this type.
Contributing Content

Only one CAD document can be associated to a given Windchill part using this type, but the same CAD document can be associated to multiple parts with this type.

Some build rules containing a representation build link (that is, for Owner, Contributing Image, and Contributing Content associations) require the part to be iterated during a build. In other words, associating or disassociating a part and CAD document having those associations requires that the part be checked out and checked back in.
