your example, the height values are near zero, so the shape is near the XZ plane. The Transform adds 3193 to Y, shifting the ElevationGrid 3 kilometres up. On the other hand, the house doesn’t have a Transform, and its Y coordinates range from -9 to -3; therefore,
the house is 3 kilometres below the ground.</span><o:p></o:p></p>
