Help with noob task

Hey guys,

I’ve no idea what I’m doing, but I’m looking for some way to take an anatomical 3d human body and/or skeleton model and modify the shape, bend, and warp parts of it to point out joint and structural degradation…

I thought Blender might be easy if I could download a free/cheap 3d model somewhere… although considering what I need to do is relatively simple. It doesn’t necessarily need to be 3d, Is there some more rudimentary method you would recommend…

If I could draw, I’m sure I could use ms paint, lol…

anyway,

Thanks for your time.

P.S - Apologies if I’m posting in the wrong spot.
