Hi, I am having an issue using Rhino inside Revit to generate a model within an existing Revit project template. When I try to generate beam elements using the Add Beam component - using any beam family (also note that Add Column works fine) - I get a ‘Parameter is Read Only’ error, where the beam is generated in Revit but is not recognised as a Revit component and as such I am unable to use the beam components to alter offsets or add text parameters.
The strange part is, when I run the same script with the same families in a new, blank Revit template there is no error. Is there anything within a Revit file which could be causing this sort of error? Thank you
