The IfcRelAdheresToElement is an objectified relationship between an element and one to many surface feature elements that adhere to the surface of the element. The relationship is defined to be a 1 to many relationship. The IfcRelAdheresToElement establishes an aggregation relationship between the main element and a sub ordinary surface feature.
The IfcRelAdheresToElement implies a surface interface between the geometric bodies of the element and the surface feature . As with all decomposition relationships it determines:
- existence dependency - the RelatedSurfaceFeature cannot exist without the RelatingElement
- hierarchical and non-cyclical relationship - the IfcRelAdheresToElement can only alter a single IfcElement
- no spatial containment - the IfcSurfaceFeature as related element never participates in the hiearchical spatial containment relationship IfcRelContainedInSpatialStructure
