ARROWHEAD toggles on or off the current ARROW style on the nearest end of a selected path or arc. If you apply an arrowhead to a line, CC3 turns that line into a path.
To reverse the operation, apply the arrowhead command again to the entity, or select the UNDO command (Edit > Undo).
To change the style of the arrow, invoke the ARROWHEAD STYLE command (Specs > Arrowhead Style).
