Semantic definitions at the entity
Entity definition

IfcRelConnectsPortToElement is a relationship between a distribution element and dynamically connected ports where connections are realised to other distribution elements.

Ports contained in different elements are connected to each other using the IfcRelConnectsPorts relationship.

NOTE  See IfcRelNests for its usages to represent an ordered collection of ports that are contained by an element and relevant subtypes of IfcDistributionElement for examples and port use definition sections.

HISTORY  New entity in IFC2x2.

IFC4 CHANGE  The objectified relation IfcRelConnectsPortToElement is now specialized for use of dynamically connected ports. For fixed ports, use IfcRelNests instead. Previously this objectified relationship IfcRelConnectsPortToElement defined the relationship that is made between a port and the IfcElement in which it is contained. It is a 1 to 1 relationship. The IfcRelConnectsPortToElement established a whole part relationship between the element and its port. The port is used as the means to connect to other ports in other elements.
