Global Mapper v25.0

Export Surface to KMZ

I am trying to export a surface view to a KMZ, have tried both raster & vector, but having trouble getting it to show the correct elevation.  I imported the surface to GM15.2 from a LandXML file (from Civil3D).  I Generated a Triangulated Elevation Grid.   This example is a fill area I am trying to show in Google Earth.  They show up, just without the correct elevations.

    When exporting to KML/KMZ raster, Global Mapper exports a raster image that gets draped on the surface in Google Earth.  It is not an elevation grid, per se.  KML does not support an actual elevation grid.

    Thank you for the response.  I am not exporting a raster, I am exporting a vector.  My original source is a Civil3D surface model, which I've opened in GM using LandXML.  GM does a good job in the 3D View but the aerials I have available don't show what I need.  The area for this project has the 3D trees which helps present this task the best.

    I am doing just a simple fill (mound), I can do surface triangles (3d), a 3d grid, 3d contours, about anything, I was hoping GM would be able to help me somehow display this in Google Earth?
