Dont forget AutoCAD WS is on the Android as well for free and that is a perfect mobile DWG viewer and markup.
Yes, and I need to get out here in the NG more often. :-)
Isn't AutoCAD WS cloud based? So, if you do not have access to the cloud, it does nothing but rain on your perfect app.
Is it just too hard for Autodesk to write a simple viewer app for Android, or do they simply not care to?
