I'm having issues exporting CAD files using the 4D Edit in RG. The 4D edit display in RG does not have any visuals either, I can only see my models and the robot in the main workcell view. Files are not created when I 'synchronize'; there is nothing in the tpgl export folder. However, there is a exportlog.txt file that says 'connection failed'. I'm not sure if this is a related issue. Any suggestions?
