I have some windows (actually they are curtain walls that I am using as windows) that are above my cut plane, that I want to show dashed in the floor plan view. I set the primary range top to include the windows, but they do not appear. I would use a plan region, but for two reasons - I don't want to show the wall cut, and I have a door below one of the windows that I want to show cut properly. How do I get the windows to just appear as dashed lines?
