I took a 3d modeling class in college but that was years ago. I think the software was LightWare.
A few years ago I got Pinch ViaCad 2D/3D but haven't really done much with it. Strangely, not as many tutorials on line as I thought there would be. Also, my current computer isn't as powerful as I think it needs to be. I'm planning on getting a new one this summer, one powerful enough to run all my graphics and other programs I need.
I would like to get a 3D printer at some point. I have an idea for a cosplay I'd like to do, and some 3D printed parts would come in handy.
Finally, I think you need a certain number of posts, before you can post pics and links. I think its 50.
Lightwave is a common 3d modelibg program and costs body parts to use. I recommend blender 3d, freeware.
In general you'll need a good GPU in your system for rendering 3d now. I recommend at least a fx 1660 or higher, look for one with as many CUDA cores as you can get.
