I am trying to replace the cross-sections of columns that were placed in a Revit model. Does anyone know how to achieve that ?
Like most objects in Revit, it is a simple as using the Element.SetParameterByName node. I have been trying to use a short Python script to use the same placed instances and give them a new type. I am getting a weird error “TypeError: expected FamilySymbol, got FamilySymbol”.
You can see attached my script.
