Multiple selected objects share same rot. axis?

That worked great! It's not a problem seeing as it's just a small room, luckily. (And that my PC is hard to strain xD).

also, if you move these combinations while you have align to grid checked, it could make them change position very slightly, but it will be noticeable. You may want to double check that! Also, if the combination disappears (which is a common bug) just restart the editor.
