Refresh modified overlays
I seartch GM and the forums but didn't find a method to refresh overlays. For instance, I had an AutoCAD drawing overlaid on a DEM. I then modified the AutoCAD drawing (changed lineweights and some other minor things) in AutoCAD. What I was looking for was a way to force GM to re-read that .dwg file. This happens automatically if I close and then reopen the .dwg but it would be handy to be able to force the re-read from the Control Centre.
