The Export STL command allows the user to export any loaded elevation grid data sets to a STL format file for use with some CAD systems.
When selected, the command displays the STL 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 Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
