Q:

Is there a good free DWG viewer for Mac OS X?

There are new Autodesk products (AutoCAD LT or similar) for Mac OS and iOS, but I couldn't find a simple free DWG viewer for Mac.

A:

AutoCAD WS is a free app on the Mac App Store. I've never tried it.

A:

A360 Viewer
AutoCAD's A360 Viewer is a browser based tool for viewing DWG files:

A360 Viewer Free online viewer - View designs in more than 50 file formats, including .dwg, right in your browser—no downloads or plug-ins needed.

LibreCAD
LibreCAD is open source, free, and can read and write DWG files.
