I sure this has been asked a lot of time, but I have been wondering how you can turn doodads upside down. Is there a hotkey for that like for deforming ("+","-")? I know how to swivel and deform and stuff, but how can you actually place for example a house so that the roof touches the ground and the floor is in the sky. I know its a bad example, I just can't think of anything better. Also please excuse my bad English.
