5.4.3.33 IfcRelConnectsWithRealizingElements

Verbindet Elemente mit Befestigungen - Relation

IfcRelConnectsWithRealizingElements defines a generic relationship that is made between two elements that require the realization of that relationship by means of further realizing elements.

An IfcRelConnectsWithRealizingElements is a specialization of IfcRelConnectsElement where the connecting operation has the additional attribute of (one or many) realizing elements that may be used to realize or further qualify the relationship. It is defined as a ternary relationship.

EXAMPLE  It may be used to describe the attachment of one element to another where the attachment is realized by a 'fixing' element such as a bracket. It may also be used to describe the mounting of one element onto another such as the requirement for the mounting major plant items onto builders work bases and/or anti-vibration isolators.
HISTORY  New entity in IFC2x2.
