We use both Solidworks and Autocad and have also used Edrawings for general users to view and print drawings. I have never has any problems in the past. Since I have switched to Autocad 2013 the dwg files have not been accessible through Edrawings 2013. The dwg files that have not yet been opened with Autocad 2013 still work fine. I was really hoping that the problem would be resolved with the latest 1-30-2013 release of the viewer but I still have the issue. I have nearly 40 users of Edrawings and need to find a solution. Any help would be appreciated. I tried to get support through my VAR but the only solution was Draftsight and I would rather not manage two different programs.
