Here is a basic mating question. Attached is a simple example of a problem that I am having. "Concept 6" is intended to be 3" above the top plane and concentric to "Stem". I have also put a tangent mate with "Lipstick Dummy" , Concept A is intended to be free to rotate around the stem. AS soon as I rotate Concept A, the tangent mate is corrupted. Is there a way to stop that from happening? Is my approach faulty?
