The other benefit of using CAD is that with programs such as Solidworks and AutoCAD you can go to the FRC website or other parts suppliers such as Andymark and download 3D CAD files of parts from the FRC kit or from the company's catalog.

On 467 we used a big plotter printer to print out 2-D CAD images which we then cut out and then attached to our sheet aluminum. The benefit of this is that we could more reliably make precision cuts and drill more precisely.
More precision= less wasted material= more money for other stuff.
