AutoCAD Returns to Mac, Debuts on iPad

If there was any doubt about the Mac resurgence, you can put that aside. Autodesk (s ADSK), the San Rafael, Calif.-based software company behind 3-D design, engineering and entertainment software AutoCAD, is releasing a Mac version of its software. Like many companies, AutoCAD has shunned the Mac platform for a long time, betting instead on the more dominant Windows platform.

The accompanying graphic aptly reflects the rebounding fortune of the Mac platform. Recognizing growing Mac sales — especially among the design and engineering communities — has brought Autodesk into the Apple (s aapl) fold. In its most recent quarter, Apple sold 3.47 million Macs. Nearly 5000 folks participated in the beta testing of the native version of the AutoCAD for Mac, and Autodesk is simultaneously launching a new, free app for iPad, iPhone and iPod touch that would allow owners of AutoCAD software to edit and share files on these devices.
