a nest of bees in graphic design

When you add an arrowhead to an open path, the arrowhead appears at either the start of the path or the end. However, you might want to change the placement of the arrowhead from one end of the path to the other. The quickest way to do so is to choose Object > Paths > Reverse Path. That will change the start of the path to the end and the end to the start. You can also click the Reverse Path icon in the Pathfinder panel.
