3D Surface modeling and rendering
Have been using Auto CAD 2002 for a decade testing more modern and affordable programs, but been disappointed whit there lack of stability as the models get more complicated. Rhino 5.0 seems to be the middle of the road price wise and is both stable and much more advance surface modeling and rendering than my out date Auto CAD. I have upgraded my computer whit dedicated Nvidia 2100K grafic card, improving real time rendering tremendusly - just a real nice experience to work whit.
This is a great CAD program - highly recomended.
