Some of our topo maps are published without gridlines as part of the map image. If you are using the map in digital form you can easily use the route tool to measure bearings and distances, and the map appears much cleaner and de-cluttered without them.
However, when you print the map, grid lines are needed for traditional navigation techniques. No problem! Just enable the "Draw Grid" option in the print dialog. You can select the grid system under the Mode, Position Format menu.
Not that printing the grid lines is only available in the Windows PC app. If you are on a Mac and you need grid lines, we recommend running the Windows PC app under Parallels instead of the native Mac app.
