Hello everyone

I am trying to apply a node with cross-product lacing with a list with 3 levels (@L3). However, i am a bit confusedâ€¦ I am just basically trying to find the intersection of a set of surfaces with itself (@L2), but i have other lists too (@L2 too).

In other words :

What i have :

- List : (@L3)
- 0 List (@L2): 7 Surfaces
- 1 List (@L2): 4 Surfaces

What i want :

- List : (@L4)
- 0 List (@L3) : 7x7 surfaces intersections
- 1 List (@L3) : 4x4 surfaces intersections

Does anyone know how to do that without using a Python Script node ?

Best regards
