Autodesk has issued a press release confirming that AutoCAD will be available in Mac OS X system in October at a MSRP of $3,995. Autodesk also announced AutoCAD WS a mobile application for iPad and Iphone which will let you view, edit and whare DWG files on your iPad, iPhone or iPod touch.

Autodesk is bringing its AutoCAD architecture, design, and engineering software back to the Mac OS after an 18-year absence, the company announced this evening. But the company plans to do more than offer a Mac OS X version of AutoCAD: It says it will release a free version of the software, dubbed AutoCAD WS, for the iPad, iPhone, and iPod Touch that lets users review, edit, and share AutoCAD files on those popular mobile devices.

The company says AutoCAD for Mac OS X is a fully native application, using Mac OS X libraries and native UI features. AutoCAD for Mac takes full advantage of Mac OS X, including graphical browsing of design files with Cover Flow and use of multitouch gestures on Mac notebooks, the Magic Mouse, and the Magic Trackpad for intuitive pan and zoom features, a spokesman said. User-experience design patterns, such as the visual approach to drawing and layout management, have also been incorporated into AutoCAD for Mac.
