IfcRelAdheresToElement Class
Syntax
C++
class IfcRelAdheresToElement : public IfcRelDecomposes;

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 hierarchical spatial containment relationship IfcRelContainedInSpatialStructure
  • NOTE: In contrary the IfcRelAggregates relationship establishes an aggregation of equal parts to a whole.
