The IfcRelCoversBldgElements relationship is an objectified relationship between an element and one to many coverings, which cover that element.
NOTE The definition of IfcCoverings include both the coverings of building elements, such as flooring or cladding. and the covering of distribution elements, such as wrapping or sleeving.
The IFC specification provides two relationships:
NOTE This relationship is now deprecated and replaced by IfcRelAggregates.
NOTE This relationship is now deprecated and replaced by IfcRelContainedInSpatialStructure.
Whether the relationship between the covering and the space, or between the covering and the element, is regarded as primary, has to be determined within the context of a model view definition.
HISTORY New entity in IFC1.5
DEPRECATION The relationship IfcRelCoversBldgElements shall not be used anymore, use IfcRelAggregates instead.
