Finding net surface area via "HB Label Faces"

Hello everybody,

I would like to extract net surface area of (the wall in orange) without the window.

However, by using “HB Label Faces” component, I get the wall area without cutting the window out.

Shouldn’t it be the same as the visualised model ? Or there is another way to get the net surface area ?

@chris : any advice ? :slight_smile:

Many thanks in advance !
