IfcDistributionChamberElementType

Definition from IAI: The element type IfcDistributionChamberElementType defines a list of commonly shared property set definitions of a distribution chamber element and an optional set of product representations. It is used to define a distribution chamber 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. A distribution chamber element is a formed volume used in a distribution system, such as a sump, trench or manhole. Distribution chamber element types may be exchanged without being already assigned to occurrences.

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