Flipping Angle Mates

I cannot find a workaround to fix angle mates. My problem areangle mates that flip direction with no apparent reason. I mightset an angle mate in one direction in an assembly, and it isreversed when inserted as a subassembly. I try using planes and notsurfaces to specify the angle mate.

Am I doing something wrong? Is there some way around this? NothingI do don't seem to work.

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