Parameters

theResults result of check - list of failed checks and sub-shapes.

◆ DistantShapes()

SequenceOfPairOfShape DistantShapes	(	in CheckResults	theResults,
		in long	theShapeType,
		in long	theSubShapeType,
		in double	theTolerance
	)

find remote objects (sub-shape on a shape). Avaliable types:

vertex far from edge;
vertex far from face;
edge far from face

Parameters

theResults	result of check - list of failed checks and sub-shapes.
theShapeType	Type of shape.
theSubShapeType	Type of sub-shape.
theTolerance	tolerance, by default used tolerance of sub-shape.

◆ UpdateTolerance()

double UpdateTolerance ( in GEOM_Object theShape )

Compute possible tolerance for the shape, minimize tolerance of shape as well as tolerance of sub-shapes as much as possible.

Parameters

theShape Shape for update.

◆ ShapeProximityCalculator()

GEOM_Object ShapeProximityCalculator	(	in GEOM_Object	theShape1,
		in GEOM_Object	theShape2
	)

Get the calculator for the proximity value between the given shapes.

Parameters

theShape1,theShape2 Shapes to find proximity.

Returns: The calculator object.

◆ SetShapeSampling()

void SetShapeSampling	(	in GEOM_Object	theCalculator,
		in GEOM_Object	theShape,
		in long	theNbSamples
	)

Set number sample points to compute the coarse proximity.

Parameters

theCalculator	Proximity calculator.
theShape	Shape to be samples.
theNbSamples	Number of samples points.

◆ GetCoarseProximity()

double GetCoarseProximity ( in GEOM_Object theCalculator )

Compute coarse value of the proximity basing on the polygonal representation of shapes.

Parameters

theCalculator Proximity calculator.

Returns: Proximity value.

◆ GetPreciseProximity()

double GetPreciseProximity ( in GEOM_Object theCalculator )

Compute precise value of the proximity basing on the exact shapes.

Parameters

theCalculator Proximity calculator.

Returns: Proximity value.

◆ IsDone()

boolean IsDone ( )

inherited

To know, if the operation was successfully performed.

◆ SetErrorCode()

void SetErrorCode ( in string theErrorID )

inherited

Set the operation error code.

Parameters

theErrorID is a string describing the error occurred

Note: This method is supposed to be used only by interfaces inheriting from IOperations.

◆ GetErrorCode()

string GetErrorCode ( )

inherited

Get the operation error code.

◆ StartOperation()

void StartOperation ( )

inherited

Opens a new transaction.

◆ FinishOperation()

void FinishOperation ( )

inherited

Closes the previously opened transaction.

◆ AbortOperation()

void AbortOperation ( )

inherited

Aborts the previously opened transaction.
