jewelry design with CAD

I want to learn the official CAD software available for jewelry designers. I have some unusual pieces knocking around that I’d like to get out on computer.

Legwork is going to have to go into this goal, as the price on this particular software is $$$$$$$. I am going to have to try some back doors to get my hands on a copy (legally – as in working out borrowed computer time from a company or student) before I can think about affording my own.
