To create a drawing:
Ⅵ Cross three ruled lines on your first stroke. A drawing box appears.
Subsequent strokes in or touching the drawing box become part of the
drawing. Drawings that do not cross three ruled lines will be treated as
writing.
Note: You may want to change the zoom level so that you can more
easily work on or view your drawing. Tap Tools and then tap a zoom level.
The drawing box indicates
the boundaries of the drawing.
