I had mentioend Acad for Mac the other day, but it struck me to be so interesting, I haveto talk about it again. It even sounds odd to say AutoCAD and Mac together. Lets hope they are developing other apps. for Mac like Revit. Other Autodesk apps like 3ds Max Design will run under Mac's Boot Camp. So atleast that is a step in the right direction.
Here is anAutodesk link to AutoCAD for Mac: http://usa.autodesk.com/adsk/servlet/pc/index?id=15421056&siteID=123112
