I have been using the Broderbund 3D Home Architect Deluxe to design our new home. This is a wonderful tool, as Rob said! I had a technical problem with it at one point, and E-mailed to them. They (almost immediately) replied with a 4 page instruction sheet! The software can be bought at WalMart for a mere $49.95 and is worth ten times that much. Good Luck!!
