Auto Associate Conditions
The auto associate parts functionality works in accordance with the following conditions:
For a successful association, the document must be checked out and have no existing associations, and the part must be checked out. Auto Associate automatically checks out the found or created part to the workspace. Documents and associated parts remain checked out to the workspace after association.
While searching parts, if more than one part per document is returned, then the Auto Associate command ignores the document and an error message is shown in the Event Management utility.
Using a multi-selection, if you select parts and checked in documents along with qualified CAD documents, the parts and checked in CAD documents are ignored by the Auto Associate action. If none of the selected objects are valid candidates for the command, a status message appears to inform you.
If you select a newly created drawing document, the system searches the database for the model associated with the drawing. If the model is found, the system creates a Described By link between the part and the drawing, and an owner association between the part and the model. If the model is not found, a message stating this is reported in the Event Management utility.
