Surface.Difference doesn't work as expected

Hello everyone,

In my script i am using Surfaces in combination with the Surface.Difference node.
However the problem i am having right now is that this node cuts off my adjacent surfaces as well (not only the overlapping ones.)

Is this intended? If yes how would someone get around this?

Surface.Difference doesnt work as i expect.dyn (41.0 KB)

Hi @Daan
I think it is the regular behaviour of the difference node : if you remove “nothing” (no overlapping) from “something” you get “something”.
You can filter the adjacent surfaces by using Geometry.Intersect, if the result is not a surface you drop it.

Thanks for the tip! Will try the Geometry.Intersect node

Hi everyone,

The solution with geometry.intersect did not work for me, however i did create a similar approach, but now my list structure is wrong at the output of the group.

Surface.Difference Group.dyn (53.6 KB)

I don’t know how to keep the structure the same, i tried losing the List.Clean nodes, but then i only get null values as output.

Thanks in advance!
