Out of axis

[rhciv]

this is not necessarily a bug. I have a house model that is a composition of at least 3 fully developed models. I duplicated the floor plane at distance on vertical axis above and if I draw a line from corner to corner on blue axis it misses the duplicate plane's corner.
Either I had a small rotation on a component that I built off that became a major piece. Anyone had one go corkscrew?
Nice job on the forum guys. Can't wait to check it out.
