I'd like to control pitch, yaw and roll (as well as x,y,z but that's easy) of a part in an assembly through a design table.  It's not as simple as just mating to planes with angles because the planes are coupled, things can get over contraint errors very easily.

I'm looking for an independent method of controlling the pitch, yaw and roll.  BTW I've tried a 3D layout sketch.  It was complicated and worked for a little bit, then exploded.  I need something reliable.

Thanks,

Matt
