There is an organization called the "Intellicad Technology Consortium" (www.intellicad.org) whose members are software companies that have created something called "Intellicad" as a dwg-compatible CAD competitor to AutoCAD. At least one of these, Progesoft (www.progesoft.com) is in the process of creating a Linux version, so perhaps a Mac OS X version isn't far behind.Originally Posted by nick.51679
