Geography/Coordinates
The option is available to display screen coordinates in longitude, latitude instead of x,y. This option can be set by selecting Oneline Display Options from the Onelines ribbon tab or the Options ribbon tab. The following options are located under the Geography/Coordinates category.
Map Projection in Use
The map projection indicates which projection has been selected for inserting objects on the oneline. Users should be careful to not change a projection once one has been established. Otherwise, there is the risk that different objects will be inserted with different projections.
Show longitude, latitude coordinates when showing x, y coordinates
When this option is checked and a map projection other than None (x,y) is selected, longitude, latitude coordinates will be displayed anywhere that x,y screen coordinates are normally displayed. This option will only be enabled when a map projection other than None (x,y) has been selected.
