To draw an ellipse by entering three points
1 On the Draw menu, click Circle, Ellipse Axes, or click the Ellipse Axes
button on the All-In-One toolbar.
2 Click a point. A rubber-band line appears beginning at the entered point.
3 Click another point to determine the length of the major axis. A rubber-
band ellipse follows the axis movement of the pointer.
4 (optional) Press and hold CTRL to slant the ellipse.

To draw an elliptical arc that fills a rectangle
1 On the Draw menu, click Arc, Elliptical Rectangle, or click the Elliptical
Arc Rectangle button on the All-In-One toolbar.
2 Click a point that defines one corner of the rectangle. A rubber-band
rectangle follows the movement of the pointer.
3 Click a point that defines the diagonal corner of the rectangle. A rubber-
band line appears from the ellipse’s centerpoint and follows the pointer,
letting you define the start and end angles.
4 Click the start angle. Notice the start angle appears on the edit bar.
5 Click the end angle of the elliptical arc.
