Rhino.Inside offers the function to change element parameters, however for some reason I cannot address the ParamterKey Structural Material. This material should be generated from the Revit material library. As you can see, also the Parameter Key gets an error.
I also tried it with a create material component, but this also did not help.
So, how to correctly assign a (structural) material from a Revit material library to an element?
Hopefully someone knows the answer!
