IfcRelCoversSpaces

Definition from IAI: 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, and
- IfcRelCoversSpaces to assign coverings to spaces

Which relationship should be applied has to be determined by the context of the project or application .

> NOTE View definition may determine the necessity to use either of the two relationship elements

> HISTORY New Entity in Release IFC 2x Edition 3.
