Hi, I found that HVAC zone object is not exported to IFC. Even in the IFC export option, I specify " HVAC Zone" to be exported to "IfcSpace". It does not work From the online documentation of IFC 2X3, HVAC zone should belong to IFCZone entity. However, Revit MEP cannot export IFCZone. Any solutions to get HVAC Zone which is different from space/rooms
Thanks, Allen
