Hello together, I have a list of 245 points (red dots) and a list of 16 points (green dots) and I want to filter the indices that lie between the green points (in the blue borderings

) from the list of 245 points. The points are sorted by their Y coordinate. With the command “MemberIndex” this would have to work but I don’t know how to do this for this case. Can someone help me?Here is the part of the GH_File
