I am a newbie. I had a project about design blades of vertical axis turbine.But i draw 3D not good.Please help me! I use Autocad 2007.Thanks for helping.
I think you can only do surface job with autocad, no solid model. (except simple helix? i dont remember the 2007 version).
It will be very easier if you use a true 3d software like solidwork, Inventor...
Choose a recent version: it's more ease for learninng (it is more intuitive).
Thank you so much i will try to solidwork or inventor
