I'm currently working to automate the classification of equipment elements in Revit for IFC export using Dynamo. The goal is to map each element to its appropriate IFC classification based on a standardized equipment code and assign the result to the "Export to IFC As" parameter.
However, it seems that the “Export to IFC As” parameter cannot be set programmatically, even when supplying valid IFC type names (e.g., IfcPump, IfcTransportElement) via Dynamo, the parameter value remains unchanged. It appears the field only accepts values from the dropdown menu and rejects any input not manually selected in the UI.
Is there any officially supported method to assign this value programmatically?
