I'm completely in agreement about what Ted said. I' have been testing
3D programs for two years, before to choose the best for my way of
working. Rhino 3.0 results the one which gave me the best
performances at a nice price and in a very short time learning.
Now ,after I have been using it every day for one year, I'm a
goldsmith and a professional designer too, you may see some results
at http://gallery.mcneel.com/?language=it&i=11420 and at

Hope to be useful and be free to write me if you want to wish to
have some work-tracks. @Gus
