1. I cannot see the room separation lines that I added some time ago on a floor plan. They are there, but I could not see them in the VG so I could turn them "on" temporarily. How these are made visible on a floor plan?
2. I have some "rooms" created previously in some open plan areas with room separation lines. The "rooms" area definitions have changed somewhat with further designs, and I can pick each individually and they highlight with the diagonal crosses, but I could not modify each to the new intended layout. How to stretch and adjust these formerly created rooms?
I already found out how to turn the lines on: VG/Model Categories/Lines/Room Separator, and then once turned on, these can be edited (i.e., moved, etc.).
The tricky part was where to find them after a long period of non-use. There is a dedicated header there under Model Categories named "Rooms", which turns on the Rooms colors and crosses, and that is where I logically thought they would be located, but they were not, and that is where I originally looked for them and could not find them, and did not realize that these were secretly located (super secretively, I would say) instead under "Lines", which I forgot. Looking at some handwritten old notes in one of my books I found their location.
