Hi,

Try turning on the previews of all your nodes to know exactly with what you are trying to deal with at each moment.

I suspect it is not working correctly that your elements do not have the parameters you are looking for.

The easiest way to do what you want to achieve would be, I guess, to select all the elements at a level, then all the ceilings, then use the List.SetIntersection node

Hi, give a try with List.Contains node (remember to use Cross Product Lacing):

Hello luca,
I lace (Cross Product) the List.ContainsItem node and I got this ! any help.

by the way I have Dynamo 1.3.2 copy, is this make any difference ?

In the upper graph you are filtering by Ceiling. Try Ceilings
And use StringFromObject to go from Category to just the text string.

With a Flatten after List.Contains should work, or you can play with levels (arrow close to mask > use levels > L2)

Super its work perfectly

Thanks alot
