﻿GetBoundedVolumes Method ()
Calculates the volume of an area defined by several points.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 10.3.488.0

Syntax

C#
```public SurfaceVolumeInfo GetBoundedVolumes(
Point3dCollection polygon
)```
Visual Basic
```Public Function GetBoundedVolumes ( _
polygon As Point3dCollection _
) As SurfaceVolumeInfo```
Visual C++
```public:
SurfaceVolumeInfo GetBoundedVolumes(
Point3dCollection^ polygon
)```

Parameters

polygon
Type: 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.

Remarks

This method is equivalent to the overloadded method with datumElevation = 0.0.

Examples

CopyC#
``` 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();
9double elevation = 30.5;
10
11SurfaceVolumeInfo surfaceVolumeInfo = surface.GetBoundedVolumes(polygon, elevation);
12write(String.Format("Surface volume info:\n  Cut volume: {0}\n Fill volume: {1}\n Net volume: {2}\n",
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",
19    surfaceVolumeInfo.Cut, surfaceVolumeInfo.Fill, surfaceVolumeInfo.Net));```

Exceptions

ExceptionCondition
System..::..ArgumentException Thrown when the passed in polygon can't construct a closed polygon.
