Syntax

C#

public SurfaceOperationAddContour AddContours(
	Point3dCollection points,
	double midOrdinateDistance,
	double maximumDistance,
	double weedingDistance,
	double weedingAngle
)

Visual Basic

Public Function AddContours ( _
	points As Point3dCollection, _
	midOrdinateDistance As Double, _
	maximumDistance As Double, _
	weedingDistance As Double, _
	weedingAngle As Double _
) As SurfaceOperationAddContour

Visual C++

public:
SurfaceOperationAddContour^ AddContours(
	Point3dCollection^ points, 
	double midOrdinateDistance, 
	double maximumDistance, 
	double weedingDistance, 
	double weedingAngle
)

Parameters

points: Type: Point3dCollection
A collection of 3d points used to create contours.

midOrdinateDistance: Type: System.Double
When the contour is defined from a polyline with curves, the midOrdinateDistance value is used to tessellate the arcs in the polyline.

maximumDistance: Type: System.Double
Specifies the maximum distance between vertices. If the distance between vertices on a contour is greater than the maximumDistance, then points are added along the contour at equal intervals that are less than or equal to the maximumDistance.

weedingDistance: Type: System.Double
The distance value for the weeding factor.

weedingAngle: Type: System.Double
The angle value for the weeding factor.

Remarks

The weeding factors ignore both vertices that are closer together than the distance factor and vertices that deflect less than the angle factor.

Exceptions

Exception	Condition
System.ArgumentException	Thrown when: The count of points is less than two. midOrdinateDistance <= 0.0, maximumDistance < 0.0, weedingDistance < 0.0 or weedingDistance >= maximumDistance
