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.

THAT green arc.
That segmented green line represents a boundary of a terminal area or other such navigation deliniation. It is part of the MAP display along with the little blue navaid symbols. If the display was "zoomed" out (Range changed) you would probably see a full circle or occasionally some other complex shape representative of the area boundary that it represents.
