I know some of you guys use CAD software so I though I'd offer a couple books I have here.
1) Autocad 2005 User Manual (Shrink wrapped). This is the original book that comes with the software. It well over 400 pages.
2) SDC Parametric Modeling with Autodesk Inventor 9. www.schroff.com
This is an excellent tutorial for people wanting to learn Inventor.
I am asking $20 each
