Clean node doesn't work

[nlardiesU5J7A]

Hi all!

I’m trying to clean up a list with RoomBoundaries.CleanNulls but nothing happens. I tried with Clean node and similar… It’s for a simple script to make a boundary line to create finish lines in each room…

Thanks in advance

@nlardiesU5J7A ,

you can also use group by key…

Thanks for reply…What do you mean? Key for “Empty List”?

@nlardiesU5J7A ,

Emtiness comes from redundant rooms, so they have 0.00m² area, you can filter your rooms by that…

i mean GroupByFunction

Sorry but it doesn’t work…there’s other option?
