7.2.3.2 IfcActuatorType

Type d'appareillage de commande
Aktor - Typ

The distribution control element type IfcActuatorType defines commonly shared information for occurrences of actuators. The set of shared information may include:

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