I cannot find a workaround to fix angle mates. My problem are angle mates that flip direction with no apparent reason. I might set an angle mate in one direction in an assembly, and it is reversed when inserted as a subassembly. I try using planes and not surfaces to specify the angle mate.

Am I doing something wrong? Is there some way around this? Nothing I do don't seem to work.

This is an old topic, but it needs some new complaining.
