#### 6.1.3.5 IfcRelCoversSpaces

| Ordnet Bekleidung / Belag einem Raum zu - Relation

The objectified relationship, IfcRelCoversSpace, relates a space object to one or many coverings, which faces (or is assigned to) the space.

> NOTE Particularly floorings, ceilings and wall coverings, such as claddings or tiling are often considered as space coverings, rather then wall or slab coverings. In some life cycle phases, such as the operation phase, the relationship is always made to the space.

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.

> HISTORY New entity in IFC2x3.

> DEPRECATION The relationship IfcRelCoversSpace shall not be used anymore, use IfcRelContainedInSpatialStructure instead.
