IVolume.Volume Property
The enclosed 3D volume.
Public ReadOnly Property Volume As Double
public double Volume {get;}
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.
public static void CalculateVolume()
{
IGeometry geometry = GetMultiPatchGeometry();
IVolume volume = geometry as IVolume;
double calculatedVolume = volume.Volume;
//calculatedVolume = 225.048
}
