You're welcome to them. As I said, I just play around with this stuff.
I had a chance to try out Maya for a while. I like how it's a bit like working with clay, and makes modelling really interesting, but I never got as good with it as I have with Rhino.
I would love to be able to try out the full version, too. The trial version gives me limited features and saves. But I can't afford the $10,000 for something that's just a toy to me
