Detailed Description

IfcVirtualGridIntersection defines the derived location of the intersection between two grid axes. Offset values can be specified to set an offset distance to the grid axis for the calculation of the virtual grid intersection.

The two intersecting axes (IntersectingAxes) define the intersection point, which exact location (in terms of the Cartesian point representing the intersection) has to be calculated from the geometric representation of the two participating curves.

Offset values can be specified (OffsetDistances). If specified, the position within the list of OffsetDistances corresponds with the position within the list of IntersectingAxes. Therefore: OffsetDistances[1] sets the offset to IntersectingAxes[1], OffsetDistances[2] sets the offset to IntersectingAxes[2] OffsetDistances[3] sets the offset to the virtual intersection in direction of the orientation of the cross product of IntersectingAxes[1] and the orthogonal complement of the IntersectingAxes[1] (which is the positive or negative direction of the z axis of the design grid position).

The image below illustrates two offset distances specified where the virtual intersection is defined in the xy plane of the grid axis placement.

The image below illustrates three offset distances specified where the virtual intersection is defined by an offset (in direction of the z-axis of the design grid placement) to the virtual intersection in the xy plane of the grid axis placement. The distance of the offset curve (OffsetDistances[n]) is measured from the basis curve. The distance can be positive, negative or zero. A positive value of distance defines an offset in the direction which is normal to the curve in the sense of an anti-clockwise rotation through 90 degrees from the tangent vector T at the specified point. (This is in the direction of orthogonal complement(T).) This can be reverted by the SameSense attribute at IfcGridAxis which can switch the sense of the AxisCurve.

The image below illustrates an example of a negative offset where the figure shows the side of the offset. IntersectingAxes[1].AxisCurve is an IfcTrimmedCurve with an IfcCircle as BasisCurve and SenseAgreement = TRUE. IntersectingAxes[1].SameSense = TRUE. OffsetDistances[1] is a negative length measure

Member Function Documentation

◆ comparedToEarlyImpl()

virtual bool OdIfc4x4::IfcVirtualGridIntersection::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.

◆ getAttr() [1/2]

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.

◆ getAttr() [2/2]

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.

◆ getInstanceType()

virtual OdDAI::Entity * OdIfc4x4::IfcVirtualGridIntersection::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.

◆ getIntersectingAxes()

void OdIfc4x4::IfcVirtualGridIntersection::getIntersectingAxes ( OdDAIObjectIds & IntersectingAxes ) const

Gets the value of IntersectingAxes attribute. This attribute represents two grid axes which intersects at exactly one intersection. If attribute OffsetDistances is omitted, the intersection defines the placement or ref direction of a grid placement directly. If OffsetDistances are specified, the intersection is defined by the offset curves to the grid axes.

Parameters

IntersectingAxes [out] Receives the intersecting axes.

◆ getOffsetDistances()

void OdIfc4x4::IfcVirtualGridIntersection::getOffsetDistances ( OdArray< double > & OffsetDistances ) const

Gets the value of OffsetDistances attribute. This attribute represents offset distances to the grid axes. If specified, it defines virtual offset curves to the grid axes. The intersection of the offset curves specify the virtual grid intersection.

Parameters

OffsetDistances [out] Receives the offset distances.

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.

◆ intersectingAxes()

OdDAI::ListOfOdDAIObjectId & OdIfc4x4::IfcVirtualGridIntersection::intersectingAxes ( )

Returns the value of IntersectingAxes attribute. This attribute represents two grid axes which intersect at exactly one intersection. If OffsetDistances attribute is omitted, the intersection defines the placement or ref direction of a grid placement directly. If OffsetDistances is specified, the intersection is defined by the offset curves to the grid axes.
