SurfaceGetBoundedVolumes(Point3dCollection) Method

Calculates the volume of an area defined by several points.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.292
Syntax
public SurfaceVolumeInfo GetBoundedVolumes(
	Point3dCollection polygon
)

Parameters

polygon  Point3dCollection
The polygon specifies the area where the volumes are calculated. Since the polygon should be a closed one, the start point and the end point must be the same. There must be more than 3 points in the Point3dCollection.

Return Value

SurfaceVolumeInfo
Exceptions
ExceptionCondition
ArgumentException Thrown when the passed in polygon can't construct a closed polygon.
Remarks
This method is equivalent to the overloadded method with datumElevation = 0.0.
Example
 1// Create a region that is a polygon inside the surface.
 2// The first and last point must be the same to create a closed polygon.
 3// 
 4Point3dCollection polygon = new Point3dCollection();
 5polygon.Add(new Point3d(20, 20, 20));
 6polygon.Add(new Point3d(20, 80, 15));
 7polygon.Add(new Point3d(80, 40, 25));
 8polygon.Add(new Point3d(20, 20, 20));
 9double elevation = 30.5;

13    surfaceVolumeInfo.Cut, surfaceVolumeInfo.Fill, surfaceVolumeInfo.Net));
14
15// If you do not specify an elevation, 0.0 is used:
16// 
17surfaceVolumeInfo = surface.GetBoundedVolumes(polygon);
18write(String.Format("Surface volume info:\n  Cut volume: {0}\n Fill volume: {1}\n Net volume: {2}\n",
