There is list A: containing multiple surfaces (red)
There is list B: containing multiple surfaces (green, openings)
I would like to trim the surfaces in list A, with the surfaces in list B.
And return a list C: with the trimmed surfaces + the unaffected surfaces.
There is a way to do it with the region Difference --> Boundary --> surface. However, when I do this I am ‘loosing’ the surfaces which lay on a different plane. (don’t fully understand why this is the case).
This while I would like to have a list in the end containing:
Trimmed surfaces + All surfaces which are unaffected.

Is there a generic way of selecting all the surface which are not affected by the Region difference tool?
Or maybe there is even a better way to do it
