Add arrowheads to lines

  1. Select an object or group (or target a layer in the Layers panel).
    Note: You can add arrowheads to a Live Paint group as a whole, but not to individual paths within Live Paint groups.
  2. Choose Effect > Stylize > Add Arrowheads or Filter > Stylize > Add Arrowhead.
  3. Choose from various arrowhead designs for the start and end of the line by clicking the forward and back buttons below the Start and End arrow boxes. The start and end of the line refer to the order in which the line was drawn.
  4. To rescale the size of an arrowhead, enter the percentage you want in the Scale text box. This scales the arrowhead relative to the stroke weight of the line.
  5. Click OK.

    If applied as a filter, the resulting arrowheads are distinct objects grouped with the line; the arrowheads can be edited and moved like any other grouped object. If applied as an effect, the arrows are similar to brush strokes; that is, the arrows change location, direction, and color along with the line, but they cannot be edited separately.
