IfcFlowTerminal

Definition from IAI: The distribution flow element IfcFlowTerminal defines the occurrence of a permanently attached element that acts as a terminus or beginning of a distribution system (e.g., air outlet, drain, water closet, sink, etc.). A terminal is typically a point at which a system interfaces with an external environment. Its type is defined by IfcFlowTerminalType or its subtypes.

An IfcFlowController can be either aggregated into the definition of the IfcFlowTerminal using the IfcRelAggregates relationship, or referenced using the IfcRelConnectsPorts objectified relationship.
