Hello @Joana ,
Welcome to Dynamo Community,

Yes it is possible, you can group the elements on the basis of X & Y position and ignore the Z component.

You are missing list level lacing, you need to make sure you compare each “inside” list in the second List.SortByKey.

Hi! I am trying to do something similar. I want to group the columns in the same location (x==x, y==y, but z can be different). With your help I already did the groups but now I need to know how to give the same name to the elements of each group. [image]
