By default a PLS-CADD XYZ file imported into Global Mapper will load as vector point features. Enable the Configuration option to Load as Lidar Cloud Data in Configuration > General > Vector Formats to load data from this format as a point cloud.
The Export PLS-CADD XYZ File command allows the user to export any loaded elevation grid data sets to a PLS-CADD XYZ format grid file. These grid files can be used with the PLS-CADD software application.
When selected, the command displays the PLS-CADD XYZ Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
