7.5.3.28 IfcDuctSegmentType

7.5.3.28.1 Semantic definition

The flow segment type IfcDuctSegmentType defines commonly shared information for occurrences of duct segments. The set of shared information may include:

  • common properties with shared property sets
  • common representations
  • common materials
  • common composition of elements
  • common ports

It is used to define a duct segment type specification indicating the specific product information that is common to all occurrences of that product type. The IfcDuctSegmentType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcDuctSegmentType are represented by instances of IfcDuctSegment. Refer to the documentation at IfcDuctSegment for supported property sets, materials, composition, and ports.
