u To draw an ellipse
Note
When you draw an ellipse, you need to specify the following three elements: center point,
Point 1 and Point 2. Point 1 is used to define the minor axis (nearest point on the edge from
the center point), and Point 2 is used to define the major axis (farthest point on the edge from
the center point).

Drawing Figures
(1) Tap [Draw] and then [Ellipse].
• This highlights the ellipse button on the toolbar.
(2) Tap the point you want to specify as the center point.
(3) Tap the point you want to specify as Point 1 (minor axis).
• This causes a line to appear between the center point and Point 1.
• Instead of tapping, you could drag the stylus from the center point to Point 1, viewing
the line that is drawn as you do.
(4) Tap or drag to the point you want to specify as Point 2 (major axis).
• This causes the ellipse to appear.
Center Point ····· A
Point 1··············· B
Point 2··············· C
When AC is shorter than AB, Point 1 becomes the major axis and Point 2 becomes the minor
axis.
