I need your help.
There are two groups of surfaces. The first group has 84 surfaces and the second group has 76 surfaces. All of the second group surfaces are included in the first group. It means that there are 8 surfaces which are not intersected. I want to select the 8 surface in grasshopper.
I have tried “subtract”, “solid difference” but they didn’t work.
again, my purpose is selecting red surfaces without green surfaces in grasshopper. Please, give me some good idea.
