IfcFlowSegment
What is IfcFlowSegment?
IfcFlowSegment represents a straight or curved section of a distribution system that carries fluid, air, or energy from one point to another. This is the parent type for duct segments, pipe segments, and cable segments.

Common Properties
Properties commonly found on IfcFlowSegment elements in IFC models.
Real-World Usage
Flow segments make up the majority of MEP elements by count in most models. Construction teams track segment installation by system and zone, verifying routing, support spacing, and insulation requirements.

IfcDuctSegment
IfcDuctSegment represents a straight or curved section of ductwork that carries conditioned air, exhaust, or ventilation air within an HVAC system. Duct segments connect to other segments, fittings, and terminals to form a complete air distribution network.
MEP ElementIfcPipeSegment
IfcPipeSegment represents a straight or curved section of piping that carries water, gas, steam, or other fluids. Pipe segments are used in plumbing, hydronic heating/cooling, fire protection, gas supply, and industrial process systems.
MEP ElementIfcCableSegment
IfcCableSegment represents a section of electrical cable or wire that carries electrical power or data signals. Cable segments run through cable trays, conduits, or directly through building elements and connect to outlets, panels, and equipment.
Abstract TypeIfcFlowFitting
IfcFlowFitting is the abstract supertype for connection elements between flow segments — elbows, tees, reducers, transitions, and other fittings that join or redirect sections of duct, pipe, or cable tray.
