Associating CAD Documents to Parts
A recommended practice is to associate Windchill parts with CAD documents at the time of creation. However, there are at least two reasons why that practice might not be followed:
The CAD documents were created in the workspace by the Save and Upload command in Creo Parametric, not using the New CAD Document window invoked from the workspace.
In this case, the workspace provides the Auto Associate command that allows you to select multiple CAD documents, and then create and associate enterprise parts for those documents with a single click. You can also associate CAD documents to existing parts.
* 
The preference Operation > Auto Associate > Store New Parts with CAD Documents, when set to Yes, specifies that the storage location of new part created during Auto Associate be the same as its associated CAD document. By default, the preference is set to No.
Enterprise parts intended to correspond to the CAD documents have already been created in Windchill.
In this case, the Edit Association command allows you to select a CAD document and then search or browse for the appropriate enterprise part to which to associate it. The Edit Association command also allows you to start with a part and find an appropriate CAD document. The use of both commands is detailed in the following topics.
