IfcElectricalAppliance
Definition from IAI:
This class defines common electrical appliances found in a
typical AEC/FM facility. Electrical Appliances generally consist
of electrical devices which 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 R2x. Geometry Use Definitions The geometric representation of IfcElectricalAppliance is 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: 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.
ISSUES: See issues and change log for changes made in IFC R2x.
