Autodesk Forge :In case of 2D .dwg drawings is space/region selection possible? in .rvt files the region/space selection is possible can we have a similar selection in .dwg files also? from 1st pic if we select a particular room the selection should look as in the second pic is that possible?
It's not possible. In a 2D drawing, that region is like empty space, you can't select it.
