IfcFlowFittingType

Definition from IAI: The element type IfcFlowFittingType defines a list of commonly shared property set definitions of a flow fitting and an optional set of product representations. It is used to define a flow fitting 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 flow fitting type is used to define the common properties of a flow fitting that may be applied to many occurrences of that type. A flow fitting is a device that is used to interconnect flow segments or other fittings within a distribution system, such as a tee in a ducted system that branches flow into two directions, a junction box in an electrical distribution system, etc. Flow fitting types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

The occurrences of the IfcFlowFittingType are represented by instances of IfcFlowFitting or its subtypes.
