When inserting a part into a multibody part file, we are given the option of "transfer" of axis, plane, cos thd., and surface. When I click plane option the planes of the inserting part show up. But if I choose axis or surface nothing happens. But is suppose to happen? I think I am transfering in the planes of the inserting part, ok. but what about surface,axis, cos thd? Any help is much appreciated.
