[QUOTE="Blowby, post: 1125189, member: 711"] Different levels of CAD software from 2D wireframe to NURBS surfacing. Autocad is a good starting point with the 3D basic modeling tools. Inventor which brings in a new design paradigm with parametric driven solids and sketches. Limitations are complex surface geometry so the type of modeling (parts) should drive your decision. SolidWorks has the same parametric method with a little more surface shape capabilities but is limited to complex non prismatic shapes. Next up the line is a complex surfacing/parametric and solid package but the cost and learning curve is up there beyond a one person or small shops budget. I work in all levels using different packages and the order I described lays out the easiest to learn to the hardest. Most of the complex modeling I do is in ThinkDesign and hyperCAD for 5 axis machining using hyperMILL. Try to enroll in a local community college and obtain a student version. Good luck and post up and I will follow this to help if I can. [/QUOTE]
