6.1.3.36 IfcSlabType
6.1.3.36.1 Semantic definition
The element type IfcSlabType defines commonly shared information for occurrences of slabs. The set of shared information may include:
- common properties within shared property sets
- common material information
- common material layer definitions
- common shape representations
It is used to define a slab specification (i.e. the specific product information, that is common to all occurrences of that product type). Slab types may be exchanged without being already assigned to occurrences.
The occurrences of the IfcSlabType within building models are represented by instances of IfcSlab.
Informal Propositions
- The material assignment, if provided using the IfcRelAssociatesMaterial relationship, shall not reference the IfcMaterialLayerSetUsage. Use IfcMaterialLayerSet instead.
