Mold CAD

I am looking to get started making my own plastics. I have a buddy who is pretty good toolmaker. Does anyone out there design their own molds? If so can you recommend a good free CAD program to draw them in? I have experience with AutoCAD and Solidworks. Also, would anyone be interested in selling their CAD of molds they have designed?

try contacting Rick Jacob's baits he might be able to help you also you can get on the form on his site and ask questions I do design my own molds but I sent a drawing to the mold maker they usually drawn up in the computer.
