OK, asking you experts out there. I have AutoCAD available again and now I want to create surfaces and solids to bring in as .mpc or other file for carving. I have the ai2mpc routine which has worked great for 2d stuff but now I want to try something a little more advanced. I've searched the forum, but my skills at putting in the right search terms have been unsuccessful. Can anyone point me to a couple post or give me some general direction?

Thanks in advance,
Tracy
