Definition from IAI: An IfcElectricApplianceType defines a
particular type of common electrical appliance found in a typical AEC/FM
facility. Electrical Appliances generally consist of electrical devices that
are not a fixed part of the building but instead can be moved from one space to
another and are powered with electricity.
HISTORY: New entity in IFC R1.0.
Renamed from IfcElectricalFixture in IFC 2x. Renamed as
IfcElectricalApplianceType in IFC 2x2.
Use Definitions
An IfcElectricApplianceType is a subtype of IfcFlowTerminalType
that provides for various forms of electrical appliance.
Usage of IfcElectricApplianceType defines the parameters for one
or more occurrences of IfcFlowTerminal. Parameters are specified through
property sets that are enumerated in the IfcElectricApplianceTypeEnum
data type.
Geometry Use Definitions
The geometric representation of an occurrence of an
IfcElectricApplianceType (instance of IfcFlowTerminal) of a particular
IfcElectricApplianceTypeis given by the
IfcProductDefinitionShape, allowing multiple geometric representations.
Included are:
Local Placement
The local placement is defined in the supertype IfcProduct. It is
defined by a subtype of IfcObjectPlacement which can define an absolute
placement, relative placement, or grid reference, with each defining the local
coordinate system referenced by all geometric representations. The
PlacementRelTo relationship of IfcLocalPlacement, if given, shall point
to the same IfcSpatialStructureElement which is used in the
ContainedInStructure inverse attribute, or to a referenced spatial structure
element at a higher level. If the relative placement is not used, the absolute
placement is defined within the world coordinate system.
Informal propositions for local placement:
- If the LocalPlacement is specified, then all aggregated components
should use this placement as their relative placement.
Standard Geometric Representation
Currently, the use of attribute driven geometry for this class is not
supported. The standard geometric representation is defined using explicit
geometry.
B-Rep Representation
The faceted B-Rep capabilities (with or without voids) shall be
supported for B-Rep representation.
