6.2.3.19 IfcFlowSegmentType

Type de tronçon d'installation fluides
Verteiler (allgemein) - Typ

The element type IfcFlowSegmentType defines a list of commonly shared property set definitions of a flow segment and an optional set of product representations. It is used to define a flow segment specification (the specific product information, that is common to all occurrences of that product type).

A flow segment type is used to define the common properties of a flow segment that may be applied to many occurrences of that type. A flow segment is a section of a distribution system, such as a duct, pipe, or conduit, that typically has only two ports. Flow segment types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

Occurrences of the IfcFlowSegmentType are represented by instances of IfcFlowSegment or its subtypes.
