CurveCreateArcBlend Method

public static Curve CreateArcBlend(
	Point3d startPt,
	Vector3d startDir,
	Point3d endPt,
	Vector3d endDir,
	double controlPointLengthRatio
)

Public Shared Function CreateArcBlend ( 
	startPt As Point3d,
	startDir As Vector3d,
	endPt As Point3d,
	endDir As Vector3d,
	controlPointLengthRatio As Double
) As Curve

Parameters

startPt

Type: Rhino.GeometryPoint3d
Start of the arc blend curve.

startDir

Type: Rhino.GeometryVector3d
Start direction of the arc blend curve.

endPt

Type: Rhino.GeometryPoint3d
End of the arc blend curve.

endDir

Type: Rhino.GeometryVector3d
End direction of the arc blend curve.

controlPointLengthRatio

Type: SystemDouble
The ratio of the control polygon lengths of the two arcs. Note, a value of 1.0 means the control polygon lengths for both arcs will be the same.

Return Value
