Are there any simple 3D modellers out there that I can download (maybe off Kazaa or something)? By simple I mostly mean a system where you can drag on the shapes in a window rather than manually set coordinates.

For example right now for computer science I'm working in a group of 3 and I have to draw 3D-looking circles. My partner threatens to render them in KeyCAD (suppositively a simple version of CAD, he showed me how to use it but it's hard) and reduce me to tears if I couldn't do it myself. :guns1: I could try using a photo editor to add shadows to it but even if I succeed here in the long run I need a 3D modeller that I can learn to draw skyscrapers for this site, etc. , amongst other things. :D

can a mod move it to Your Skyscrapers instead, where the drawing tips are supposed to be? (also more views there)

Done. :)
