Bryster? I wasn't mocking other modelers, although they are all quite inferior to Rhinoceros in terms of raw power. By all I mean all of the ones I've used : Amorphium, Ray Dream Studio, Lightwave, 3DStudio Max, Amapi, Truespace, Wings, Blender, Bryce, ZBrush... Rhinoceros has inherent functions and can control many automated processes in a machine shop. It can be used for rapid-prototyping, such as making prototype car models, or to actually, mathetmatically, make a perfect screw (out of metal), for example. Or a screwdriver. Or a chain link. Or an entire plastic toy, such as a Transformer. Rhino was created for many purposes, but making REAL objects with it is one of it's best features. Head over to the Rhino galleries and you will see what I mean.
