Tutorial for 3d CAD???

Woohoo! I just finished setting up my Van Norman Model 12 to CNC. I have zero backlash in both ballscrews, x and y axes, and reduced the old z axis' acme screw down to 4 thousandths backlash , which I certainly can live with.

Now I am at a loss...although I use Autocad daily for my building electrical designs, I have no clue how to do 3d parts designs...I suspect it's not a huge transition but can anybody steer me in the direction of some resources online to get through this quickly? I would rather avoid coursework and/or textbooks, but as a last resort....thanks to all who helped me with this retrofit, it wa much appreciated.

P.S. I saw a big CNC mill at the scrapyard waiting to be cut up for scrap on Saturday....can't remember the mfgr's name, but it sure was tempting to bring that 2 ton beast home with me...
