There are 2 beams of bridge, I am trying to get the bridge beams’ geometry in Dynamo and union them as one geometry, then using the node “FamilyType.ByGeometry” to create a family type. Dynamo shows all succeed but I get an empty family type, so I open the family file, there is no geometry too. I’m using Revit 2022, Dynamo version is 2.10.1. Is anyone get this issue?

Hello @XIN.DU.BIM and welcome to the forum :wink: seems your template is generic adaptive, does it work if you try genericmodel.rft ?
