Hello everyone;

does anybody try to set ductless return system in Revit? I have difficulties figuring that out because the return system includes transfer ducts and the air terminals stay ductless and therefore Revit doesn't display the system airflow in the tag by the AHU. Instead, it displays the flow from the duct and that is null. Is anybody know the workflow of ductless return system and how to fix this.
I appreciate your contributions.

Thank you,
