This is a grid in the Main Display Window displayed at the same level as the ground plane.
The precision of the grid will adjust depending on how close the viewpoint is to the ground. There are four sizes of grid, of which only two are displayed at a time. The spacing of the gridlines depends on the chosen units:
The display colour for each of these gridlines can be changed in the Display Preferences
Also, when 'Snap to Grid' is on, routes will snap to gridpoints when drawn. If you do not want to snap to a smaller scale gridline, then use the mouse wheel to zoom out until the smaller scale gridlines disappear. You will then be able to snap to the larger scale gridlines.
