To export a single contour line:
- Select the contour map and go to the Levels tab in the Property Manager.
- Set the Level method to Advanced and click the Edit levels button.
- Change the contour levels so that only the level you want to export exists.
- Click OK. The map should show you only that contour line.
- Turn off the axes in the Object Manager (uncheck them) so you only see the contour line on the screen.
- Then go to File | Export and export the contour line to a BLN file (or whatever file format you desire).
If more than one contour line was drawn for that level, and hence is exported to the BLN file, you can remove the extra lines in Surfer 9 or 10 by:
- Go to Map | New | Base Map.
- Select the BLN file and click Open. The BLN file will be loaded as a base map.
- If more polylines or polygons exist than what you want, you can simply select the extra polylines or polygons and press the Delete key on the keyboard to delete them.
- Once the BLN file shows just want you want it to, turn off the axes for the base map in the Object Manager (uncheck them).
- Go to File | Export and re-export the BLN file.
