HB Room doesn't work with internal floors/walls. The volume is not closed

I have created a building with multiple levels which I want to be able to change. However I use the HB Room component because I created everything out of surfaces, but it can’t recognize anything from the interior surfaces and it gives me no volume. However, it recognizes the exterior walls, the roof, and the ground but I want to separate the levels of the building. Also even though it recognize the internal floor/ceilings,it is still 1 room and not 1 room per floor.

Hi @Dimitra3, Welcome to the forum.

You can upload the file to Dropbox, Google Drive, etc. and share the link. It is unlikely that anyone can help you without a sample file.
