IfcDistributionFlowElement
What is IfcDistributionFlowElement?
IfcDistributionFlowElement is the abstract supertype for elements that participate in fluid or energy flow within distribution systems. It covers flow segments (pipes, ducts, cables), flow terminals (outlets, fixtures), flow controllers (valves, dampers), and flow moving devices (pumps, fans).

Real-World Usage
This abstract type is the parent for all active MEP components that carry or control the flow of air, water, electricity, or gas. MEP engineers use this classification to isolate building services from the structural and architectural model.

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.
MEP ElementIfcFlowTerminal
IfcFlowTerminal represents an endpoint of a distribution system where fluid, air, or energy is delivered to or collected from the space. This is the parent type for air terminals, sanitary terminals, light fixtures, outlets, and other endpoint devices.
Abstract TypeIfcFlowController
IfcFlowController is the abstract supertype for devices that regulate flow within distribution systems. This includes valves (water, gas), dampers (air), switches (electrical), and other control devices that modify the rate, pressure, or direction of flow.
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.
