From the user POV it doesn't appear Autodesk know Windows Mobile exists (or for that matter in terms of tablets even Metro Full/RT Windows). Pity as in some markets outside the US it is starting to gain traction.
Does anyone know a workaround? Can't even use the web based version of Autodesk 360 because Firefox nor Chrome has a WM8 version.
Autodesk lack of Windows Phone support sucks.
There is a 3rd party viewer for DWFx 2D only (not DWF or 3D DWFx). It requires your file to be in the root directory of your Onedrive or Google Drive cloud. Look for Pocket Plans in the Phone App store.
