Hi, I`m studying Dynamo for a couple of weeks and decided now to try to produce something for Revit. The idea is to place one family instance where objects (pipes/cable trays/ducts) intersects with walls from a linked model. As I did not find anything that looks like this in the internet, I thought of this workflow: 1 - Run Interference check to collect a list of objects intersecting wall by ID 2 - Select objects by ID (from interference check list) 3 - Place family in the intersection. The problem is that I cant find a node that let me select objects by a list of IDs, does anyone knows how can I do it?

[image] Selection - Selecting Elements using element IDs Revit 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)

Select by ID
