I'm looking for something that is kind of like Auto Desk Inventor, but along the lines of free. The program that I'm looking at costs 995$. I'm completely serious and that is for one person personal use. The Google version is not what I'm looking for. I checked I need the ability to extrude, round out objects, make really detailed designs. Blender Might work but i have no clue how to use it. But its not a CAD program. I'm Being really pick about this as well, mostly because I want the ability to create things. So does anyone know of a free or cheaper 3d CAD program maybe specifically for engineering?
