public Ifc4x1::IfcElementComponentType(Class Ifc4x1::IfcElementComponentType)
IfcDiscreteAccessoryType: public Ifc4x1::IfcElementComponentType¶
Definition from IAI: The element type (IfcDiscreteAccessoryType) defines a list of commonly shared property set definitions of a discrete accessory and an optional set of product representations. It is used to define a supporting element mainly within structural and building services domains (i.e. the specific type information common to all occurrences of that type). The occurrences of the IfcDiscreteAccessoryType are represented by instances of IfcDiscreteAccessory. The IfcDiscreteAccessoryType is a specialization of the general building element component type to represent different type of structural and building service related auxiliary elements. HISTORY New entity in IFC Release 2x2
IFC 2x4 change: Attribute PredefinedType added.
General usage The exact type information of the IfcDiscreteAccessoryType is given in the ElementType attribute inherited from IfcElementType. Standard type designations are provided for guideline below. The list is not exhaustive and the list of definitions may be extended based on local national extensions.
