a lot of reports (here & here) on the autodesk announcement about autocad on the mac, check out the TV commercial here – uses flash so will not work on your ipad & iphone!
now the only thing left waiting for is revit for mac.
on a sidenote: although we are really looking forward to a cool version of autocad (as per the commercial), we also hope that the code name sledgehammer refers more to the peter gabriel song than the eighties TV series… either way autocad was absent from the mac for almost as long as these references are old.
