IfcActuatorType

Definition from IAI: An IfcActuatorType defines a particular type of actuating device that is typically used in a control system such as a building automation control system.

HISTORY: New entity in IFC 2x2

Use Definitions

An IfcActuatorType provides for all forms of actuator.

Usage of IfcActuatorType defines the parameters for one or more occurrences of IfcDistributionControlElement. Parameters may be specified through property sets that are enumerated in the IfcActuatorTypeEnum data type.

Property Set Use Definition:

The property sets relating to the IfcActuatorType defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcActuatorType are part of this IFC release:

Pset_ActuatorTypeCommon: property set for the properties common to all types of actuator, if available
Pset_ActuatorTypeLinearActuation: specific property set for the properties of a linear actuator, if available
Pset_ActuatorTypeRotationalActuation: specific property set for the properties of a rotational actuator, if available
Pset_ActuatorTypeElectricActuator: specific property set for the properties of an electrical actuator, if available
Pset_ActuatorTypeHydraulicActuator: specific property set for the properties of an hydraulic actuator, if available
Pset_ActuatorTypePneumaticActuator: specific property set for the properties of a pneumatic actuator, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
