Surfer BLN
The Export Surfer BLN command allows the user to export any loaded vector data sets to a Surfer BLN format file used by Golden Software's Surfer package to specify breaklines.
When selected, the command displays the Surfer BLN Export Options dialog which allows the user to set up the export. The dialog consists of an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.
