Please find attached a door and window combination that I made as a test a year ago or so. There are nested windows on each side of the door which have Visibility Parameters for right and left. When this is inserted into a project and the Visibility Parameters are switched, the wall hole 'heals'. I can't remember how I did this. I think that I have narrowed it down to a setting in the window template but I can't duplicate it with another window/door combo. AND IT"S DRIVING ME CRAZY. Anyone know what I'm forgetting?
