How to generate a surface mesh from a Point Cloud of a Digital Terain Model.

Steps to Accomplish

1. Open the Point Clouds dialog ( File > Point Clouds ) and attach the Point Cloud file ( File > Attach )
2. Highlight the attached file in the Point Clouds dialog and select File > Export

   

3. On the 'Export Point Cloud' dialog set the Format to ASCII Files (*.xyz ) and select OK to save.

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 Tools > Dimensions > XYZ Text >Import Coordinates tool  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.
