The element type IfcTrackElementType defines commonly shared information for occurrences of track elements. The set of shared information may include:
- common properties within shared property sets
- common material information
- common profile definitions
- common shape representations
It is used to define a track element specification (the specific product information that is common to all occurrences of that track element type). Track element types may be exchanged without being already assigned to occurrences. Occurrences of the IfcTrackElementType are represented by instances of IfcTrackElement.
The inherited attribute ElementType shall be provided, if the PredefinedType is set to USERDEFINED.
