How to generate a surface mesh from a Point Cloud of a Digital Terain Model.
Note: Use the ' Density ' and ' Region Filter ' ( Use the 'Clip' tool on the Point Clouds dialog to define region ) options on the Export Point Cloud dialog to define the level of detail / area required.
4. Optional: Detach the *.pod file from the model
5. Use the tool Import Coordinates (Drawing > Annotate > Terrain Model > Coordinates) to place Points in the model at the coordinates defined in the exported *.xyz file.
6. Use the 'Mesh From Point' tool to generate a surface mesh from the imported Points.
