Detailed Description

A curtain wall is an exterior wall of a building which is an assembly of components, hung from the edge of the floor/roof structure rather than bearing on a floor. Curtain wall is represented as a building element assembly and implemented as a subtype of IfcBuildingElement that uses an IfcRelAggregates relationship.

The geometric representation of IfcCurtainWall is defined using the following multiple shape representations for its definition: Axis: A two-dimensional open curve (for restrictions see below) defining the axis for the curtain wall. This is an optional representation for curtain walls. Body: A surface model or boundary representation model representation defining the 3D shape of the curtain wall. If the IfcCurtainWall has components (referenced by SELF\IfcObject.IsDecomposedBy) then no independent shape representation with RepresentationType = 'Body' is defined. The body of IfcCurtainWall is then geometrically represented by the shape representation of its components. The components are accessed via SELF\IfcObject.IsDecomposedBy[1].RelatedObjects. If the IfcCurtainWall has no components defined (empty set of SELF\IfcObject.IsDecomposedBy) then the IfcCurtainWall can be represented by an shape representation with the RepresentationIdentifier ='Body'.

  • Axis 2D Geometry - The following additional constraints apply to the 'Axis' representation: Geometry : IfcPolyline having two Points, or IfcTrimmedCurve with BasisCurve of type IfcLine or IfcCircle
  • Object Typing - This concept can be applied to the following resources: IfcCurtainWallType
  • Product Local Placement - The following restriction can be imposed by view definitions or implementer agreements: If the IfcCurtainWall establishes an aggregate, then all contained elements are placed relative to the IfcCurtainWall.ObjectPlacement
  • Property Sets for Objects - This concept can be applied to the following resources: Pset_CurtainWallCommon
  • Quantity Sets - This concept can be applied to the following resources: Qto_CurtainWallQuantities

Member Function Documentation

◆ comparedToEarlyImpl()

virtual bool OdIfc2x3::IfcCurtainWall::comparedToEarlyImpl ( const OdDAI::ApplicationInstance * pOther,
OdRx::Ordering & ordering ) const
overridevirtual

Early-bound version of instances comparison.

Parameters
pOther[in] Other application instance.
ordering[out] Receives the ordering (comparison) status.
Returns
true if comparison was performed, false if method has no implementation, so late-bound version could be applied.
Remarks
If the method returns true, the ordering parameter can receive one of the following statuses:
Value Description kLessThan -1 This object < Other Object. kEqual 0 This object = Other Object. kGreaterThan 1 This object > Other Object. kNotOrderable 2 This class is not orderable.

Reimplemented from OdIfc2x3::IfcBuildingElement.

◆ getInstanceType()

virtual OdDAI::Entity * OdIfc2x3::IfcCurtainWall::getInstanceType ( ) const
overridevirtual

Returns a type of a class instance.

Returns
Pointer to the <exref target=https://docs.opendesign.com/tkernel_api_cpp/OdDAI__Entity.html>>OdDAI::Entity</exref> type that determines an entity definition within a schema.

Reimplemented from OdIfc2x3::IfcBuildingElement.

◆ isKindOf()

virtual bool OdIfc2x3::IfcCurtainWall::isKindOf ( OdIfc::OdIfcEntityType entityType) const
overridevirtual

Checks whether the specified instance is the object derived from or belongs to this class.

Parameters
entityType[in] Entity to check.
Returns
true if the specified instance is the object derived from or belongs to this class, false otherwise.

Reimplemented from OdIfc2x3::IfcBuildingElement.

◆ type()

virtual OdIfc::OdIfcEntityType OdIfc2x3::IfcCurtainWall::type ( ) const
overridevirtual

Returns the type of this entity.

Returns
A value of the <exref target=https://docs.opendesign.com/tkernel_api_cpp/OdIfc__OdIfcEntityType.html>>OdIfc::OdIfcEntityType</exref> type that represents type of this entity.

Reimplemented from OdIfc2x3::IfcBuildingElement.
