I'm very impressed with freecad's capabilities - particularly that it can handle gravity and momentum. I found freecad on a website www.ar-cad.com/freecad which is authored by Aik-Siong Koh. What is his relationship to your freecad community? If your response shouldn't be expressed in public, just send me an email at (nospam)@suncitydave.org. Thank you very much. Dave
