Julia, try moi3d, a simple and powerful nurbs program.
Easy learning curve. Smart and intuitive interface. And the developer is very helpful at the forum.
That war is over... lol
Thought I'd post the proper name if anyone cares..
NURBS = Non-uniform rational bezier spline. It's just a higher degree curve than a typical bezier curve used in automotive and CAD. Actually huge pain in the derier unless under control of nurbs specific programs like SW or similar 3D nurbs based program, I'm writing this with a high fever :/
