#### 7.2.3.2 IfcCableSegmentType

| Type de segment de câble
| Kabelsegment - Typ

The flow segment type IfcCableSegmentType defines commonly shared information for occurrences of cable 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 cable segment type specification indicating the specific product information that is common to all occurrences of that product type. The IfcCableSegmentType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcCableSegmentType are represented by instances of IfcCableSegment. Refer to the documentation at IfcCableSegment for supported property sets, materials, composition, and ports.
