Hello

I’m working on both revit 2024 and revit 2021 when transfering my script to dynamo 2021 this node does not exist, is there a node that can do the same function or a package that can be installed to add it in?

Thanks

List.CountTrue followed by a n>0; codeblock

Try finding the same node in 2021, if not their List.Contains with the list at level 2 and a False item input.
