Drawing ellipses, circles, arcs, and wedges

You can draw an ellipse by dragging diagonally or by specifying three points. You can also draw a circle by specifying three points, or you can specify the center and a point on the radius.

Another way to create an ellipse is to convert a curve object. The object to be converted must have a recognizable elliptical shape to be eligible. For instructions, see "To convert a curve to an ellipse" on page 72.

Drawing an arc or wedge (pie shape) is similar to drawing a circle or an ellipse, except that you move the line end points around to create the shape.

To draw an ellipse or a circle

To draw a	Do the following
3-point circle	Click the 3-point circle tool . Drag to specify the centerline of the circle, move the pointer, and click to specify the third point.
Center-point circle	Click the Center-point circle tool . Click where you want to place the center, drag until the circle is the size you want, and release the mouse button.
Center-radius circle	Click the Center-radius circle tool . In the Circle dialog box, type a value for the radius, and click where you want to place the center point.
2-point ellipse	Click the 2-point ellipse tool . Drag diagonally until the ellipse is the size you want, and release the mouse button.
3-point ellipse	Click the 3-point ellipse tool . Drag to specify the centerline of the ellipse, and release the mouse button. Move the pointer until the ellipse is the size and shape you want, and click.

When you draw a circle, holding down the constrain key while dragging constrains the shape to the current constrain angle. See Using constrain keys for more information. Holding down the constrain key while drawing an ellipse constrains the shape to a circle.

You can draw a two-point or three-point ellipse from its center outward by holding down the Shift key as you drag (if the constrain key is Ctrl).

To draw an arc or a wedge

To draw	Do the following
An arc	Click the Arc button on the property bar. Drag in the drawing window until the arc is the shape you want.
A wedge	Click the Pie button on the property bar. Drag in the drawing window until the wedge is the shape you want.

When you draw an arc, the ellipse or circle must have an outline.

You can change the direction of a selected arc or a wedge by clicking the Geometric properties button on the property bar and clicking Direction in the Property manager docker.
