Exporting DTM Mesh and no elevation values

Hello.

I have been trying to create a Mesh DTM but whenever l export it, the mesh has no elevation values. How do l go about it?

  • Can you add some more details about how you're trying to use the "mesh"?


    It sounds to me like you're trying to export a Raster DTM to something like a Triangulated Irregular network (TIN) DTM, to be used in CAD software?


    If that's the case.....

    Export Elevation Grid to "LandXML" file format

    (Optional) - Bring the LandXML file back in to GLobal Mapper and simplify it, then export it back out as a simplified version (CAD doesn't handle massive surfaces as well as GIS)

    Ex:


    After exporting to landxml, here is the same file after importing back in (TIN matches raster grid spacing that was exported)


    Simplify TIN

    Simplified TIN:
