Well you can download blender for free and learn how to use it with tutorials. May I ask what you use Rhino for? I’m always curious how niche modellers are used, it seems like Inventor, 3D Studio, Maya, etc get all the attention.
I use Rhino for drafting mostly — a fancy version of
Auto-cad. I no longer do graphic artwork. I picked up on Rhino when it first started out== I’d tried 3-d studio max and tinkered around with Maya and Rhino was one of the cheapest because it was new. I’m running version 3, and I think they’re about to release 5. Rhino 3 runs okay on Windows 7.
I don’t really need to do any elaborate rendering— ray tracing and the like— I just like to have the 3-d models that I can take projections for plans—if needed.
