The original idea was to dump my 2d autocad drawings into Autodesk Inventor to make a 3d assembly but this is a school project and time being a factor (most of the work,design and fabrication, was done this semester, since January) I was not able to do this. We have Solidworks and Rhino here at school but because Autocad is kind of a standard in the school system that is what we are trained in.
With my limited skills at this point Autocad serves my purpose. Perhaps the next car I design (I have already started working in sketches) I will use a product like Solidworks so I can do stress analyse and easy 3d rendering to insure parts fit.
But for now I want to get this project finished and test my theories and see what works. Then I can start on a new car.
