Occurrence

When creating a Map grid, or during Scaled Output, I receive the error -
"Cannot draw a grid for map XY units in degrees if not a Lat/Lon coordinate system"

Solution

Navigate to Map>Options and ensure the Distance units are NOT set to Degrees. These can be set to meters, feet, etc.

If you wish to label the Map grid with degree units, you will need to change the Projection of the Map window, under Map>Options>Projection, to a Lat/Lon coordinate system.
