Correct Entity + Enum for Floor &Wall ducts

Hello! I am looking for the correct Entity + Enumeration for floor and wall ducts. I am inclined to say IfcCableCarrierSegment, but I am not quite certain. Despite it containing the word ‘Duct’, it doesn’t feel like the correct entity is IfcDuctSegment (looking at the entity’s description). What does everyone here think the correct entity and enum should be?


Kind regards,


I think the right entity+enum is IfcCableCarrierSegment.CABLETRUNKINGSEGMENT
