Editing the Associations of CAD Documents and Parts
Initiating the Edit > Edit Associations action causes an automatic checkout of the part objects, if they are not already checked out.
* 
Any object checked out implicitly remains checked out even if the association fails to check out the other object.
After you associate a part with all CAD documents in an assembly, you can see the association. However, Uses links between the parts are not visible until after checkin, when the Windchill build rule constructs the Uses links.
It is recommended that you associate a part with a CAD document at the time of object creation, not when you create a structure. A CAD document is said to describe a part to be included in the bill of materials, and in turn a part is described by a CAD document.
To verify the association, view the details page for either object. Selecting the Related Objects tab on the information page for a part shows the associated CAD document in the CAD/Dynamic Documents table. Selecting the Related Objects tab on the information page for a CAD document shows the associated part in the Parts table.
Once checked in, the parts you associated to CAD documents have a product structure that is visible on the Product Structure page for the top-level part.
