Definition from buildingSMART: The element type (IfcSlabType) defines a list of commonly shared property set definitions of a slab and an optional set of product 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).
NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item being an IfcMappedItem.
A slab element type is used to define the common properties of a specific slab that may be applied to many instances of that type to assign a specific style. A slab type can be used for a floor slab, a roof slab, a stair landing or a ramp flight. Building element types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.
The occurrences of the IfcSlabType are represented by instances of IfcSlab, or IfcRampFlight.
HISTORY: New entity in Release IFC2x Edition 2.
