SurfaceDefinitionContoursAddContours(ObjectIdCollection, Double, Double, Double, Double, SurfaceMinimizeFlatAreaOptions) Method

Adds contours to a surface from entities in an ObjectIdCollection, and minimizes flat areas.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.292
Syntax
public SurfaceOperationAddContour AddContours(
	ObjectIdCollection boundaryEntities,
	double midOrdinateDistance,
	double maximumDistance,
	double weedingDistance,
	double weedingAngle,
	SurfaceMinimizeFlatAreaOptions options
)

Parameters

boundaryEntities  ObjectIdCollection
A collection of ObjectIds used to create contours.
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
ExceptionCondition
ArgumentException Thrown when:
  1. There are invalid ObjectIds in contourEntities.
  2. midOrdinateDistance <= 0.0 , maximumDistance < 0.0, weedingDistance < 0.0 or weedingDistance >= maximumDistance
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.
