Class properties
Property set: Attributes

Optional description, provided for exchanging informative comments.

The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute 'PredefinedType' is set to USERDEFINED.

Assignment of a globally unique identifier within the entire software world.

Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.

The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute PredefinedType is set to USERDEFINED or when the concrete entity instantiated does not have a PredefinedType attribute. The latter is the case in some exceptional leaf classes and when instantiating IfcBuiltElement directly.

Tag

The tag (or label) identifier at the particular instance of a product, e.g. the serial number, or the position number. It is the identifier at the occurrence level.

Property set: Pset_AirTerminalBoxPHistory

Air flowrate versus damper position relationship;airflow = f ( valve position).

Ambient atmospheric pressure.

Control damper position, ranging from 0 to 1; damper position (0=closed=90deg position angle, 1=open=0deg position angle).

Sound performance.
