Hi everyone.
I’m working on Rhino Inside and I’m new to grasshopper as I was using dynamo before.
So I placed planes instead of my elements to receive radiation upon but some of these planes got 2 points and some others got 1. (My goal is to have only one point per plane so I can return the values from Ladybug back to the elements, but of course the lists are messed up due to unmatching number of points/lists/results)

Perhaps there is a way to simplify the planes even more to get 1 point instead of 2? I already tried making them simplified as possible but it partially worked for some reason…

Just managed to find a solution.
Used the node “closest point” which was perfect as it picked only one closest and their index which I used to filter the results list!

it seems that you are running it from a revit document. You should simplify it before posting so other people can open and check it without too much trouble.

in any case, glad it worked out for you, that’s the most important.
