Dueller, I use Google Sketchup. Download it and play around, it is pretty intuitive. People use it to model buildings for Google Earth, and lots of other things, they do remarkable work. I've only used it to mock up home improvement projects. It is handy to be able to look at something from every angle, check the sightlines, etc. One of these days I'd like to measure my whole house and model it. But who has the time?
