CAD programs for APPLE/MAC

Aloha, One of the best and oldest for MAC would be FormZ. It is used
alot for architecture but is very suitable for Jewelry models. Check
it out at www.formz.com . If you want to see some output from FormZ,
check out, www.familyjeweler.com. Steven Pollack is the owner and at
one time did training for jewelry applications. There are a few
others or you could always run programs ported to windows, using
Virtual PC, like Rhino 3D. I hope that is of help. If I can be of
assistance, feel free to contact me.

Best Regards,
Christian
