6.1.3.29.1 Semantic definition

The IfcRelCoversBldgElements relationship is an objectified relationship between an element and one to many coverings, which cover that element.

The IFC specification provides two relationships:

IfcRelCoversBldgElements to assign coverings to elements.
NOTE This relationship is now deprecated and replaced by IfcRelAggregates.
IfcRelCoversSpaces to assign coverings to spaces
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.
