List subset / Merge entries into one list and giving false for others back

Hallo,
i have two lists where List B (50 points) is a part of List A (150 points). The entries are scatterd and not in the same order. I was trying to get a uniform list of 150 entries where i can see on which position the points from List A are in List B. But somehow i cannot match them by equal node and bool mask…

greetings
Kev

Hi @KevSch ,

Have you tried the node List.IndexOf? This node returns the first index of an item found in the list. List.AllIndicesOf returns all indices if an item occurs multiple times.

I have tried it. But it wasn`t helpful for my problem… so i did a workaround to avoid this by seperating the pointlists from the beginning into sublists,… somehow this works :smiley:
