Change MEP system name

Hello everyone,
I can’t change System name of duct. Does anyone know how to change it?


You can not change the system name of the element duct in Revit or Dynamo.
You have to change the name of the mechanical system like this:


how to get element.setparameterbynametypeorinstance? Can you help me

You can use Element.SetParameterByName instead.

element.setparameterbynametypeorinstance is from Rhythm package.

thank you so much
