def ChangeOrientation	(	self,
		theShape,
		theName = `None`
	)

Reverses an orientation the given shape.

Parameters

theShape	Shape to be reversed.
theName	Object name; when specified, this parameter is used for result publication in the study. Otherwise, if automatic publication is switched on, default value is used for result name.

Returns: The reversed copy of theShape.

Example

References geomBuilder._autoPublish(), geomBuilder.RaiseIfFailed(), and geomBuilder.ShapesOp.

◆ OrientationChange()

def OrientationChange	(	self,
		theShape,
		theName = `None`
	)

See ChangeOrientation() method for details.

Example

References GEOM_IHealingOperations.ChangeOrientation(), GEOM_IShapesOperations.ChangeOrientation(), and geomBuilder.ChangeOrientation().

◆ ProcessShape()

def ProcessShape	(	self,
		theShape,
		theOperators,
		theParameters,
		theValues,
		theName = `None`
	)

Apply a sequence of Shape Healing operators to the given object.

Parameters

theShape	Shape to be processed.
theOperators	List of names of operators ("FixShape", "SplitClosedFaces", etc.).
theParameters	List of names of parameters ("FixShape.Tolerance3d", "SplitClosedFaces.NbSplitPoints", etc.).
theValues	List of values of parameters, in the same order as parameters are listed in theParameters list.
theName	Object name; when specified, this parameter is used for result publication in the study. Otherwise, if automatic publication is switched on, default value is used for result name.

Operators and Parameters:

FixShape - corrects invalid shapes.
FixShape.Tolerance3d - work tolerance for detection of the problems and correction of them.
FixShape.MaxTolerance3d - maximal possible tolerance of the shape after correction.
FixFaceSize - removes small faces, such as spots and strips.
FixFaceSize.Tolerance - defines minimum possible face size.
DropSmallEdges - removes edges, which merge with neighbouring edges.
DropSmallEdges.Tolerance3d - defines minimum possible distance between two parallel edges.
DropSmallSolids - either removes small solids or merges them with neighboring ones.
DropSmallSolids.WidthFactorThreshold - defines maximum value of 2V/S of a solid which is considered small, where V is volume and S is surface area of the solid.
DropSmallSolids.VolumeThreshold - defines maximum volume of a solid which is considered small. If the both tolerances are privided a solid is considered small if it meets the both criteria.
DropSmallSolids.MergeSolids - if "1", small solids are removed; if "0" small solids are merged to adjacent non-small solids or left untouched if cannot be merged.
SplitAngle - splits faces based on conical surfaces, surfaces of revolution and cylindrical surfaces in segments using a certain angle.
SplitAngle.Angle - the central angle of the resulting segments (i.e. we obtain two segments if Angle=180, four if Angle=90, etc).
SplitAngle.MaxTolerance - maximum possible tolerance among the resulting segments.
SplitClosedFaces - splits closed faces in segments. The number of segments depends on the number of splitting points.
SplitClosedFaces.NbSplitPoints - the number of splitting points.
SplitContinuity - splits shapes to reduce continuities of curves and surfaces.
SplitContinuity.Tolerance3d - 3D tolerance for correction of geometry.
SplitContinuity.SurfaceContinuity - required continuity for surfaces.
SplitContinuity.CurveContinuity - required continuity for curves.
This and the previous parameters can take the following values:
Parametric Continuity
C0 (Positional Continuity): curves are joined (the end positions of curves or surfaces are coincidental. The curves or surfaces may still meet at an angle, giving rise to a sharp corner or edge).
C1 (Tangential Continuity): first derivatives are equal (the end vectors of curves or surfaces are parallel, ruling out sharp edges).
C2 (Curvature Continuity): first and second derivatives are equal (the end vectors of curves or surfaces are of the same magnitude).
CN N-th derivatives are equal (both the direction and the magnitude of the Nth derivatives of curves or surfaces (d/du C(u)) are the same at junction.
Geometric Continuity
G1: first derivatives are proportional at junction.
The curve tangents thus have the same direction, but not necessarily the same magnitude. i.e., C1'(1) = (a,b,c) and C2'(0) = (k*a, k*b, k*c).
G2: first and second derivatives are proportional at junction. As the names imply, geometric continuity requires the geometry to be continuous, while parametric continuity requires that the underlying parameterization was continuous as well. Parametric continuity of order n implies geometric continuity of order n, but not vice-versa.
BsplineRestriction - converts curves and surfaces to Bsplines and processes them with the following parameters:
BSplineRestriction.SurfaceMode - approximation of surfaces if restriction is necessary.
BSplineRestriction.Curve3dMode - conversion of any 3D curve to BSpline and approximation.
BSplineRestriction.Curve2dMode - conversion of any 2D curve to BSpline and approximation.
BSplineRestriction.Tolerance3d - defines the possibility of surfaces and 3D curves approximation with the specified parameters.
BSplineRestriction.Tolerance2d - defines the possibility of surfaces and 2D curves approximation with the specified parameters.
BSplineRestriction.RequiredDegree - required degree of the resulting BSplines.
BSplineRestriction.RequiredNbSegments - required maximum number of segments of resultant BSplines.
BSplineRestriction.Continuity3d - continuity of the resulting surfaces and 3D curves.
BSplineRestriction.Continuity2d - continuity of the resulting 2D curves.
ToBezier - converts curves and surfaces of any type to Bezier curves and surfaces.
ToBezier.SurfaceMode - if checked in, allows conversion of surfaces.
ToBezier.Curve3dMode - if checked in, allows conversion of 3D curves.
ToBezier.Curve2dMode - if checked in, allows conversion of 2D curves.
ToBezier.MaxTolerance - defines tolerance for detection and correction of problems.
SameParameter - fixes edges of 2D and 3D curves not having the same parameter.
SameParameter.Tolerance3d - defines tolerance for fixing of edges.

Returns: New GEOM.GEOM_Object, containing processed shape.
