Assembly rotation

[GordonL]

Somehow I ended up with my assembly rotated 90° Z axsis goes right to left and X and Y are vertical. Not sure what I did. The parts started out in the correct rotation. How do I get back to normal?

If all of your parts are constrained to each other and you haven't anchored any part, then all you need to do is to constrain the faces of one part to the correct base planes. If you already have a constraint to any of the base planes, you need to remove them first to 'free' up the assembly in 'space'.
