IfcFlowDirectionEnum
Definition from IAI:
This enumeration defines the flow direction at a connection
point as either a Source, Sink, or both SourceAndSink:
- SOURCE: A source of flow (e.g., it flows out of the connection)
- SINK: A flow sink (e.g., it flows into the connection)
- SOURCEANDSINK: Both a source and sink (e.g., it flows both into and
out of the connection simultaneously)
- USERDEFINED: User-defined flow direction
- NOTDEFINED: Undefined flow direction
HISTORY: New enumeration in IFC R2.0
ISSUES: See issues and change log for changes made in IFC R2x.
