Setting Space type to Plenum

Dear Developers,
Is it possible to set type of specific spaces to plenum throw dynamo?
Be informed that i tried standard set.parameter node but did not worked :smirk:
Thanks.

Can you show what you mean in the Revit properties dialog box? Perhaps provide a .rvt so we can be sure we’re all on the same page?

Dear Jacob,

Thanks.
