Preferences enable you to set distances, altitudes, and coordinates in the units of your choice. The preferences are displayed in a pane in the Map Builder under the Preferences tab. You can change preference settings at anytime and the changes take place immediately. The preference settings can affect, for example, the units of the altitude charts used in terrain analysis, the orthodromy measures drawn on the map, the scale bar, and mouse locator units.

The Date Line Wrapping option can be used to cut polygons that circumnavigate the world. Note that this option is only applied when the next reprojection occurs, for example, when you change the center of the projection.
