Syntax

C#

public SurfaceOperationAddContour AddContours(
	Point3dCollection points,
	double midOrdinateDistance,
	double maximumDistance,

)

VB

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

C++

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

Parameters

points  Point3dCollection

A collection contains the 3d points used to define contour boundaries.

midOrdinateDistance  Double

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

maximumDistance  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  Double

The distance value for the weeding factor.

weedingAngle  Double

The angle value for the weeding factor.

options  SurfaceMinimizeFlatAreaOptions

Specifies the options for minimizing flat areas on a surface.

Return Value

SurfaceOperationAddContour

Exceptions

Remarks

1. The weeding factors ignore both vertices that are closer together than the distance factor and vertices that deflect less than the angle factor.
2. If all the properties in options are false, the parameter is ignored.
