I agree with Mechanix. Work out the vertical elevations of all floors, roofs, porches, crawl spaces etc. I do this with a hand sketch that has references to the layer names. This sketch is then tacked to the wall over the monitor. The VW model setup function accomplishes this electronically; however it would be really nice if the graphic displayed during the setup routine were available for reference. As an alternate if it could be printed so I could tack it over my monitor to replace my hand sketch it would be really neat.
