Surface - Geometry does intersect return all null

Hi, I have a problem with the geometry.does intersect node as I try to intersect two surfaces and it throws me all null.
I obtained the geometry of the sanitary fixtures and the geometry of the walls, so I need to obtain the walls that intersect with sanitary fixtures, to obtain their area

I have tried with different combinations such as changing the level or changing the lacing to longest or cross product but it does not work

You’ll have to use Corss-Product lacing to ensure that everything is being checked. I’d recommend intersecting solids first (less computations) and then individual surfaces if necessary.


Ok , this is the final combination
