IfcDistributionChamberElementType

Definition from IAI: The element type IfcDistributionChamberElementType defines a list of commonly shared property set definitions of an element and an optional set of product representations. It is used to define an element 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 get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A distribution chamber element type is used to define the common properties of a distribution chamber element that may be applied to many occurrences of that type. Distribution chamber element types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

The occurrences of the IfcDistributionChamberElementType are represented by instances of IfcDistributionElement or its subtypes.
