The other way to remove all Apertures and Doors from a Room is to just pass it through the HB Apertures by Ratio component with a _ratio of zero. If the room has skylights, you may also need to do the same thing with HB Skylights by Ratio. Because these are robust ways to remove all of the apertures (albeit a little implicit I’ll admit), I don’t plan on adding other components that do this same thing.
