ND = Navigation Display.
I've never seen a "dotted green arc." However, a dashed-line green arc can be drawn by inserting a distance from a point on the FMC's Fix page. The result is a circle around the fix at the prescribed distance. Zoom in with the fix not at the center of the ND and it can easily be viewed as an arc. Commonly used to show altitude restrictions based upon a distance during approach or departures.
