Function Documentation

assignGlobalId()

bool IFCCORE_EXPORT OdIfc::Utils::assignGlobalId

(

OdIfcEntity *

pInst

)

Assigns a generated global identifier to the "GlobalId" attribute of an entity derived from an IfcRoot object.

Parameters

pInst

[in] A raw pointer to the IFC entity instance.

Returns

true if the attribute "GlobalId" was successfully assigned; otherwise the method returns false.

getAllRepresentationContexts()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getAllRepresentationContexts

(

const OdIfcFile *

pIfcFile

)

Retrieves identifiers (represented with the <link OdDAIObjectIds, OdDAIObjectIds> object) of all IfcGeometricRepresentationContext instances in a model of the specified IFC file.

Parameters

pIfcFile

[in] A raw pointer to an <link OdIfcFile, OdIfcFile> object that keeps the IFC model.

Returns

An <link OdDAIObjectIds, array of OdDAIObjectId> instances, which contain identifiers that refer to geometric representation context objects; if nothing was selected, the method returns an empty array.

getDefaultRepresentationContextsSelection()

OdDAIObjectIds IFCCORE_EXPORT OdIfc::Utils::getDefaultRepresentationContextsSelection	(	const OdIfcFile *	pIfcFile,
		bool	onlyBody = true
	)

Retrieves identifiers (represented with the <link OdDAIObjectIds, OdDAIObjectIds> object) of default IfcGeometricRepresentationContext instances, which are necessary to get the geometrical representation of a model of the specified IFC file.

Parameters

pIfcFile	[in] A raw pointer to an <link OdIfcFile, OdIfcFile> object that keeps the IFC model.
onlyBody	[in] A flag that determines that only sub-contexts with the "Body" identifiers are selected (if it is equal to true).

Returns

An <link OdDAIObjectIds, array of OdDAIObjectId> instances, which contain identifiers that refer to geometric representation context objects; if nothing was selected, the method returns an empty array.
