Parameters

points
Type: Point2dCollection
A collection of 2d 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.
options
Type: Autodesk.Civil.DatabaseServices..::..SurfaceMinimizeFlatAreaOptions
Specifies the options for minimizing flat areas on a surface.

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.

Exceptions

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