Autodesk gave Mac-using professionals a reason to celebrate back in August when it announced that it was bringing AutoCAD to the Mac and iOS devices. The company released its free, universal AutoCAD WS app for the iPad and iPhone in September, and on Friday it released AutoCAD for the Mac.

AutoCAD, a professional design and engineering application, has been a Windows PC-only product since it left the Mac 16 years ago. It’s used to model everything from mechanical parts, to architecture, to city infrastructure. It’s the Photoshop of the engineering world, now once again available to Mac users.

AutoCAD DWG files created in Windows versions are fully supported in the Mac version. And an extensive API (application programming interface) is also available to customize your workflow and integrate custom applications and other resources.

AutoCAD for Mac is available now and requires a 64-bit Intel processor and OS X 10.5.8 or 10.6.4 (Autodesk lists the full system requirements on its Website). Prices start at $3975, and there’s also a free 30-day trial available.
