IfcPrimaryFittingEnum
Definition from IAI:
This enumeration is used to identify the primary purpose of a
fitting. This is a very basic categorization mechanism
to generically identify the fitting type. Subcategories
of fittings are not enurated. The IfcPrimaryFittingEnum contains
the following:
- ENTRY: Entry fitting, typically unconnected at one port
and connected to a flow distribution system at
the other (e.g., an outside air duct system
intake opening).
- EXIT: Exit fitting, typically unconnected at one port
and connected to a flow distribution system at
the other (e.g., an exhaust air discharge
opening).
- ELBOW: A fitting with typically two ports used to change
the direction of flow between connected elements.
- TRANSITION: A fitting with typically two ports having
different shapes or sizes. Can also be used to
change the direction of flow between connected
elements.
- JUNCTION: A fitting with typically more than two ports used
to redistribute flow among the ports and/or to
change the direction of flow between connected
elements (e.g, tee, cross, wye, etc.).
- OBSTRUCTION: A fitting with typically two ports used to
obstruct or restrict flow between the connected
elements (e.g., screen, perforated plate, etc.).
- OTHER: Other type of primary fitting type not defined above.
- USERDEFINED: User-defined fitting.
- NOTDEFINED: Undefined fitting.
HISTORY: New enumeration in IFC R2.0
ISSUES: See issues and change log for changes made in IFC R2x.
