I have just made an assembly of 3 cabinets. When I rotate them in the cabinet editor the rotational center of axis is to the far right of the cabinet instead of in the center. When I use the end key to see the back of the cabinet it rotates off the screen. Is there a way to re-center the axis? What am I doing that is causing it to become off center in the first place?
First, right click and choose 'Target to Origin'. If you've moved the target at all using ctrl-t/right mouse drag it will re-center it.
If you haven't moved it, after you click 'Target to Origin' select all your pieces and move them to the target (check all your views if you want them as close to center as possible)
