Detailed Description

IfcGridPlacement provides a specialization of IfcObjectPlacement in which the placement and axis direction of the object coordinate system is defined by a reference to the design grid.

The location of the object coordinate system is specified by the attribute PlacementLocation. It is defined as an IfcVirtualGridIntersection, that is, an intersection between two grid axes with optional offsets. The axis direction of the x-axis of the object coordinate system is specified either: PlacementRefDirection = NIL: by the tangent of the first grid axis (PlacementLocation.IntersectingAxes[1]) at the virtual intersection (maybe using the offset curve, if PlacementLocation.OffsetDistances is specified); PlacementRefDirection = IfcDirection: by the explicitly provided direction information; PlacementRefDirection = IfcVirtualGridIntersection: by the tangent between the virtual grid intersection of PlacementLocation and the virtual grid intersection of PlacementRefDirection. Offsets as potentially provided in the IfcVirtualGridIntersection's of PlacementLocation and PlacementRefDirection have to be taken into account.

The direction of the y-axis of the IfcGridPlacement is the orthogonal complement to the x-axis. The plane defined by the x and y axis are co-planar to the xy plane of the local placement of the IfcGrid. The direction of the z-axis is the orientation of the cross product of the x-axis and the y-axis, i.e. the z-axis of the IfcGridPlacement is co-linear to the z-axis of the local placement of the IfcGrid.

The image below illustrates the case where PlacementRefDirection is not specified - the object coordinate system is defined by: Its location: specified by the virtual grid intersection of PlacementLocation Its x-axis direction: specified by the tangent of the first intersecting axis in the offset location of the virtual grid intersection

The image below illustrates the case where PlacementRefDirection is specified as an IfcDirection - the object coordinate system is defined by: Its location: specified by the virtual grid intersection of PlacementLocation Its x-axis direction: specified by the DirectionRatios of the IfcDirection, only the ratios for x and y are taken into account

The image below illustrates the case where PlacementRefDirection is specified as an IfcVirtualGridIntersection - the object coordinate system is defined by: Its location: specified by the virtual grid intersection of PlacementLocation Its x-axis direction: specified by the tangent of the line between the virtual grid intersection of the PlacementLocation and the virtual grid intersection of the PlacementRefDirection.

Constructor & Destructor Documentation

◆ IfcGridPlacement()

OdIfc4::IfcGridPlacement::IfcGridPlacement ( )

Default constructor for the IfcGridPlacement class.

Member Function Documentation

◆ comparedToEarlyImpl()

virtual bool OdIfc4::IfcGridPlacement::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 OdIfc4::IfcObjectPlacement.
