I can't keep my mates from flipping so I can't get the drawing finished. Everything will be locked down, no errors for a day or 2 and bam... mates flip. Re-do everything, shut the computer down, etc etc etc. Works for 10 min.. then they flip again.
I've re built the assy 3 times already. Mating plane to plane, trying different mates... I get it locked down with no errors. Then 10 minutes later they flip. I can't figure it out. Never had this problem before. Error literally says '... planes are parallel but the alignment is reversed.' How did they get reversed? What am I over looking??
