Hi @Mike.Buttery , I appreciate your response. I tried that method initially, but it placed a damper at only one wall intersection. I tested a few different data-structure inputs without success. I’ve attached the graph using Ducts.InsertDamper from archi-lab in case you want to take a look. Any ideas would be appreciated! Thanks!
