Buildings Facing a different angle

What I need is the ability to make Builings face a different angle. And in doing this, they also need to be able to pivit...So would it be possible to use the building model for a unit? And then Make it so that it can face different directions on command? :D I know there is a way to make buildings into units, using some editor (forgot the name but i have it). Just wanna know if this will mess up my map, and/or work properly.

No... just use the model of a building and put it on a unit. Give it no movement, no attack and no aquisition range and it will work.
