IfcRelConnectsPorts

Definition from IAI: An IfcRelConnectsPorts defines the relationship that is made between two ports at their point of connection. It may include the connection geometry between two ports.

IfcRelConnectsPorts is required as the means to define how instances of IfcPort connect together. Each of the port is being attached to the IfcElement by using the IfcRelConnectsPortToElement relationship. Since each element is now considered to have ports for the purpose of connection, it is necessary to achieve the actual connection by the defined approach.
