Rhino is my tool of choice, but last I looked it was about $899 for version 3. I've been using Rhino 2 for quite some time. I also have TrueSpace which I won in a contest but have never used it. I fired it up once hehehe, but I'm so familiar with Rhino, I get lazy and frustrated when confronted with an alien environment ;) Blender is free and very very nice, producing high end results but it has a higher learning curve than Rhino. ------------------------------- Calligari still sells Truespace 4 & 5 (even though the newest is version 6). Any of these will work for what you need and 4 is selling for only $199 U.S. Even 6 is very well priced at $595, but if you want to go middle of the road, 5 is value priced at $395!
