Fig 6

The following are two basic methods for drawing ellipses:
- Length and width.
- Axis and rotation angle.
Ellipse.
Creates an ellipse or an elliptical arc:

1 Choose Draw, Ellipse.

(or)
2 Choose The ellipse or partial ellipse icon
(or)

3 Type Ellipse at the command prompt
Command: ellipse
4 Type One of the following options:

Arc/Center/Isocircle/<Axis endpoint1>:
Ellipse options
Axis endpoint 1: Defines the first axis by two specified endpoints. The angle of the first axis determines the angle
of the ellipse. The first axis can define either the major or the minor axis of the ellipse.

Ellipses options
Axis end point 2: <Other axis distance>/Rotation: Specify a point or enter a distance
Arc: Creates an elliptical arc. The angle of the first axis determines the angle of the elliptical arc. The first axis can
define either the major or the minor axis of the elliptical arc.
Center : Creates the ellipse by a specified center point.
Isocircle : Creates an isometric circle in the current isometric drawing plane.
Rotation : The major axis is now treated as the diameter of a circle that will be rotated a specified amount around
the axis. You enter an angle between 0 and 89.4 degrees.
