QUOTE: Originally posted by Muddy Creek I'll second the XTrkCad program. I program and use AutoCAD for a living, but download the free model rr programs just to check them out and found XTrkCad to be easy to install and learn. It seems to do everything the free Atlas program does but is not limited to the Atlas product line. Wayne
