It's inevitable when I add / remove parts and change constraints when I create and fine tune a very complex assembly that I end up with axis and other geometry that I've added to constrain with that some become orphans. My question is how do I delete these. I get this errors if I try. I suppose they must still be attached to something but how do I figure out what. I've tried expanding all the constraints but the offending axis' do not show up in any of them. I could just leave them but I like to keep things looking nice and clean. It's another one of those things that drive me crazy.
