I am trying to add curtainwall mullions from RIR. I have a line in Rhino, and feed it to Grasshopper and organized the definition as below. And I got an error “1. RhinoInside.Revit.GH: Element cannot be pinned or unpinned.” Any idea? Thanks in advance.
Thanks very much for the reply, it was very helpful. Could you please explain more on the error message? In my mind, every input were set properly as I do in Revit, but I don’t understand what this has to do with pinned or not. On the file uploaded, for some reason its wall type wasn’t set as curtain wall, but it doesn’t make any difference even if I set it curtain wall / storefront.
