Detailed Description

IfcObjectPlacement is an abstract supertype for the special types defining the object coordinate system. The IfcObjectPlacement has to be provided for each product that has a shape representation.

The object placement can be specified: Absolute: by an axis2 placement, relative to the world coordinate system Relative: by an axis2 placement, relative to the object placement of another product By grid reference: by the virtual intersection and reference direction specified by two axes of a design grid Linear placement: by distance along a curve, with possible offsets

Object placement has to unambiguously define the object coordinate system as either two-dimensional axis placement (IfcAxis2Placement2D) or three-dimensional axis placement (IfcAxis2Placement3D).

Remarks: This definition may not be instantiated

\changes

IFC4 changes: Type of the inverse attribute PlacesObject changed from "SET OF [1:1] IfcProduct FOR ObjectPlacement" to "SET OF [0:?] IfcProduct FOR ObjectPlacement"

Member Function Documentation

◆ getAttr() [1/2]

virtual OdRxValue OdIfc4x2::IfcObjectPlacement::getAttr ( const char * attrName ) const

overridevirtual

Returns an attribute value for the specified attribute name.

Parameters

attrName [in] Name of an attribute to query.

Returns: OdRxValue object that represents a generic variant type value.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ getAttr() [2/2]

virtual OdRxValue OdIfc4x2::IfcObjectPlacement::getAttr ( const OdIfc::OdIfcAttribute attrDef ) const

overridevirtual

Returns an attribute value for the specified attribute definition.

Parameters

attrDef [in] Attribute definition to query.

Returns: OdRxValue object that represents a generic variant type value.

Reimplemented from OdIfc::OdIfcInstance.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ getInstanceType()

virtual OdDAI::Entity * OdIfc4x2::IfcObjectPlacement::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 in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ getInvPlacesObject()

void OdIfc4x2::IfcObjectPlacement::getInvPlacesObject ( OdDAIObjectIds & PlacesObject ) const

Returns the value of PlacesObject attribute. This attribute represents a set of IfcObjectPlacement instances that provide a placement and an object coordinate system for instances of IfcProduct. If an IfcObjectPlacement is shared by many instances of IfcProduct it does not apply a semantic meaning of being a shared placement that needs to be maintained. The same instance of IfcObjectPlacement could be used to reduce exchange file size.

Parameters

PlacesObject [out] Receives the value of PlacesObject attribute.

◆ getPlacementRelTo()

const OdDAIObjectId & OdIfc4x2::IfcObjectPlacement::getPlacementRelTo ( ) const

Returns the value of PlacementRelTo attribute. This attribute represents reference to object placement that provides the relative placement with its placement in a grid, local coordinate system or linear referenced placement. If it is omitted, then in the case of linear placement it is established by the origin of horizontal alignment of the referenced IfcAlignment Axis. In the case of local placement it is established by the geometric representation context.

Returns: Returns the value of PlacementRelTo attribute.

◆ inFields()

virtual OdResult OdIfc4x2::IfcObjectPlacement::inFields ( OdDAI::OdSpfFilerBase * rdFiler )

overridevirtual

Reads object's data from the specified filer.

Parameters

rdFiler [in] Pointer to a filer from which to read the data.

Returns: A value of OdResult type that contains the result of the method execution.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ isKindOf()

virtual bool OdIfc4x2::IfcObjectPlacement::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 OdIfc::OdIfcInstance.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ outFields()

virtual OdResult OdIfc4x2::IfcObjectPlacement::outFields ( OdDAI::OdSpfFilerBase * wrFiler )

overridevirtual

Writes object's data the the specified filer.

Parameters

wrFiler [in] Pointer to a filer to which to write the data.

Returns: A value of OdResult type that contains the result of the method execution.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ putAttr() [1/2]

virtual bool OdIfc4x2::IfcObjectPlacement::putAttr	(	const char *	explicitAttrName,
		const OdRxValue &	val )

overridevirtual

Sets the specified attribute with a given value.

Parameters

explicitAttrName	[in] Explicit name of the attribute to set.
val	[in] Value to set.

Returns: true if the value is successfully set for the specified attribute, false otherwise.

Reimplemented from OdIfc::OdIfcInstance.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ putAttr() [2/2]

virtual bool OdIfc4x2::IfcObjectPlacement::putAttr	(	const OdIfc::OdIfcAttribute	explicitAttrDef,
		const OdRxValue &	val )

overridevirtual

Sets the specified attribute with a given value.

Parameters

explicitAttrDef	[in] Explicit attribute definition to set.
val	[in] Value to set.

Returns: true if the value is successfully set for the specified attribute, false otherwise.

Reimplemented from OdIfc::OdIfcInstance.

Reimplemented in OdIfc4x2::IfcGridPlacement, OdIfc4x2::IfcLinearPlacement, and OdIfc4x2::IfcLocalPlacement.

◆ setPlacementRelTo()

void OdIfc4x2::IfcObjectPlacement::setPlacementRelTo ( const OdDAIObjectId & PlacementRelTo )

Sets the value of PlacementRelTo attribute. This attribute represents reference to object placement that provides the relative placement with its placement in a grid, local coordinate system or linear referenced placement. If it is omitted, then in the case of linear placement it is established by the origin of horizontal alignment of the referenced IfcAlignment Axis. In the case of local placement it is established by the geometric representation context.

Parameters

PlacementRelTo [in] PlacementRelTo attribute to set.

◆ testAttr() [1/2]

virtual bool OdIfc4x2::IfcObjectPlacement::testAttr ( const char * explicitAttrName ) const

overridevirtual

Checks whether the specified attribute is set.

Parameters
