Hi guys, I was wondering if there is any custom node to group a list of revit element according to the values of a parameter. List of elements: A B C D E F Parameter value: 1 2 1 3 2 1 result: 0- A C F 1- B E 2- D THANK YOU

yes, for example you want to group all the doors with same parameter value, in this case “Level”, use the node GroupByFunction [image] would it help?

Can we group revit element according to a parameter value?

Do we really have to eternally repeat the same things here?
