Connect Ports (FP)
Defines the connection made between two ports. In the context of a distribution system, the ports are instances of IfcDistributionPort.
For connections made between ports, the values of flow direction for each port must match. If the flow direction of the relating port is a SOURCE (outgoing), the flow direction of the related port must be SINK (incoming). If the flow direction of the relating port is SOURCEANDSINK, the flow direction of the related port must also be SOURCEANDSINK.
Results
Connection between ports is established with flow directions correctly defined.

| Determine the port from which the connection is to be made. | IfcRelConnectsPorts.RelatingPort -> IfcDistributionPort |  |
||
| Determine the port to which the connection is to be made. | IfcRelConnectsPorts.RelatedPort -> IfcDistributionPort | |
||
| An element may be used to realize the connection See illustration above |
IfcRelConnectsPorts.RealizingElement -> IfcElement | |
||
| Confirm that the flow direction of the relating and related ports match Matches must be made from relating to related as follows: SOURCE -> SINK SINK -> SOURCE SOURCEANDSINK -> SOURCEANDSINK NOTDEFINED -> NOTDEFINED |
IfcDistributionPort.FlowDirection -> IfcFlowDirectionEnum | |
||
| Set the global unique identifier | IfcRelConnectsPorts.GlobalId -> IfcGloballyUniqueId | |
||
| Assert the owner history of the relationship | IfcRelConnectsPorts.OwnerHistory -> fp_apply_owner_history | |
||
| Specify a name for the relationship | IfcRelConnectsPorts.Name | |
