It is Official Autodesk has come out with a version of AutoCAD for the Mac. After so many years (since 1982 that they released a Mac Version of AutoCAD). I believe this has been one of the most requested applications in many industries to be ported to Mac’s. Now they would get a much greater response if they released a version for Linux (they had released a Unix Version many years ago, which was a very robust application considering that it ran at 64 Bit from what I’ve read.) All the Linux fanatics would go crazy over it (including my self).
Here is their Video Release.
