I don't know how to put that better in the subject but here is kinda what i want:

1. take a box in space, any position and any orientation
   
2. Orient the box to world, using the longest edge as x, shorter edge as y and shortest edge as z
   
3. center this at the origin
   

I pretty much have this going using align vops but not sure thats the way to go so any suggestions here are welcome
Then the part I really get stuck at:

I want to take a completely different object created at the origin and move that to the original position AND orientation of the box.
but how?
