So we use a lot of parts in more than one assembly, and these parts get keyed into other parts, works fine for the first assembly then it never works again I have drawn the same part like 10 times now. So I guess the question is how do I make a part that we use in more than one Assembly. Cause we usually just off set clearance from one part to another and because of this stupid error message it takes me twice as long as I think it should.

This part has features defined in the context of another assembly, you can edit the part, but can not create any external references.. the error I get daily....
