I’m trying to get the internal surfaces of a group of walls as a list.
My first approach was to use the node “SelectFaces” from revit and it worked great. However the problem is that you have to select manually one by one the surfaces that you want to get into dynamo and this is quite time consuming specially in large models. That’s why, I tried to use the node “Element.Faces” instead. As an output, I got all the surfaces of each wall but only I’m interested in getting the internal ones. Do you have any recommendations about how this approach could be done? So far, I’ve been checking the revit API and unfortunately the only property attached to surfaces is “IsValidObject” which I can’t use for anything in my case.
