Overlapping Mass-floors elements

[Giovanni_Succi]

Hi all,
I am spending too much time on something I thought it would be basically OOTB.

I just need to find overlapping Mass-Floors, but cannot find a node that makes sense.

I wanted to use the Biomorph super-fast clash detection nodes, but they do not work with Mass-floors elements…?

Anyways, I am testing 12 mass floors of which 6 intersect, and the other 6 do not, and I am using Geometry.intersectaALL, Geometry.intersect, and Geometry.Doesintersect, but the resulting lists are not clear to me at all. It appears all floors have some intersection: are the node returning self-intersections because of the cross-product lacing?

How would you guys go about checking intersections of these elements?

The goal obviously is to avoid double counting areas…

Thank you!
