<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:navy">An ElevationGrid extends in the XZ plane, the height field containing Y coordinates of the vertices. In 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.<u></u><u></u></span></p>
