Element ID's in list

[john_pierson]

You can reselect the Revit elements with the IDs. Your input would be the "newList" output.

More info here:

Selection - Selecting Elements using element IDs

You can select Elements by their ElementId with the internal Dynamo method (as long as they are in your model). You do have to do it in a code block though. [image] in a codeblock: Revit.Elements.ElementSelector.ByElementId(elemId)
