HRESULT get_Volume(
  double* volumeValue
);
[C++]

Parameters

volumeValue [out, retval]   volumeValue is a parameter of type double

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Returns the volume of 3D space occupied by a MultiPatch. Handles closed and some non-closed MultiPatches.

Remarks

If Patches comprising a MultiPatch geometry have improperly ordered vertices such that positive faces are not pointing outwards, a negative volume will be returned. To ensure proper orientation, add vertices in a clockwise manner relative to an outside observer.

[C#]

 

        public static void CalculateVolume()

        {

               IGeometry geometry = GetMultiPatchGeometry();


               IVolume
volume = geometry as IVolume;

               double calculatedVolume = volume.Volume;

               //calculatedVolume = 225.048

        }
