Double clicking inside the corridor created a floor that goes through anything that's enclosed, even if it's meant to be open air.

Say you have an enclosed courtyard. When I double click the 2nd floor corridor that snakes round it, Sweethome automatically adds flooring over the courtyard even though the corridor is a seamless polygon.

Is there a way to "fill" only the shape I'm clicking in?
