I come back to a problem that was already detected a few years ago.
This is the floor and ceiling of a patio (room with a tree).
Here without the floor.
Impossible automatically to take into account the interior walls of the patio with doors and windows.
Here with the floor.
It seems to me that this is a bug or an undeveloped feature.
Do you have a quick tip to exclude the patio ?
Regards.

Add a temporary wall joining the exterior wall to a wall of the patio, so the room created with a double-click within that space will take into account the patio walls. Then remove the temporary wall and move the room points which touched that wall.
You may also use the tip used to draw the garden in this video.
