Flow Fittings

In this section all flow fitting related information needed to satisfy the Exchange Electrical Model - Systems will be described.

Information Needed	Actor Supplying	Functional Part
The owner history of the fitting	Electrical Design	[Model Flow Fitting (CableCarrier, PredefinedType) (FP)]
Name to extend identification of the type or occurrence	Electrical Design	[Model Flow Fitting (CableCarrier, PredefinedType) (FP)]
Description that can be used for any further qualifying information	Electrical Design	[Model Flow Fitting (CableCarrier, PredefinedType) (FP)]
Where information about fitting shape is to be exchanged as part of the building model specification, the placement and shape representation should be asserted. Shape representation is typically a representation map which is defined for the <entity> type and then referenced for each occurrence. Each occurrence specifies its own placement. Within the representation map, the particular form of the shape representation may differ according to the life cycle stage. Generally, the representations selected for the flow fitting representation map will follow the representations selected for flow segments being either: Axis Representation Body Representation o Swept solid o CSG o Bounding box o Boundary representation (Brep) \ Note that since elements may have multiple shape representations, provision of shape representations at different lifecycle stages should be considered as cumulative and not as alternative.
