	Command line: ellipse

Arc / Center / Isocircle / <Axis endpoint 1>: Specify a point (1) or enter an option

Creates an elliptical arc. The angle of the first axis determines the angle of the elliptical arc. The first axis can be either the major or the minor axis of the elliptical arc.

<Axis endpoint 1> / Center / Isocircle : Specify a point or enter c or i

Axis Endpoint 1 (ELLIPSE, Arc)

Defines the endpoint of the first axis.

Axis endpoint 2: Specify a point
<Other axis distance> / Rotation: Specify a point or enter r

Center (ELLIPSE, Arc)

Creates the elliptical arc by starting at a specified center point.

Center of ellipse: Specify a point
Axis endpoint: Specify a point
<Other axis distance> / Rotation: Specify a point or enter r

Isocircle (ELLIPSE, Arc)

Creates an isometric circle in the current isometric drawing plane.

Center of circle: Specify a point
Circle radius / Diameter: Specify a point or enter d

Center (ELLIPSE)

Creates an ellipse by starting at a specified center point.

Center of ellipse: Specify a point
Axis endpoint: Specify a point
<Other axis distance> / Rotation: Specify a distance by entering a value or locating a point (3), or enter r

Other Axis Distance (ELLIPSE, Center)

Defines the second axis using the distance from the midpoint of the first axis to the endpoint of the second axis.

Parameter / <start angle>: Specify a point (1) or enter p

Specifying a point determines the start angle of the elliptical arc.

Parameter / Included / <end angle>: Specify a point (2) or enter an option

Specifying a point for the end angle creates the elliptical arc.The Included option defines an included angle beginning at the start angle.

Included angle <current>: Specify an angle or press ENTER

Rotation (ELLIPSE, Center)

Creates the ellipse with the appearance of rotating a circle about the first axis.

Rotation around major axis: Specify a point or enter an angle value
Parameter / <start angle>: Specify a point or enter p

Move the crosshairs around the center of the ellipse and pick a point. If you enter a value, the higher the value, the greater the eccentricity of the ellipse. Entering 0 defines a circle.

Specifying a point determines the start angle of the elliptical arc.

Parameter / Included / <end angle>: Specify a point or enter an option

Specifying a point for the end angle creates the elliptical arc.

The Included option defines an included angle beginning at the start angle.

Included angle <current>: Specify an angle or press ENTER

Parameter

Parameter requires the same input as Start Angle, but AutoCAD LT creates the elliptical arc using the following parametric vector equation:

p(u) = c + a* cos(u) + b* sin(u)

where c is the center of the ellipse and a and b are its major and minor axes, respectively.

Angle / <start parameter>: Enter a valid numeric angle, second point, or option keyword
Angle / Included / <end parameter>: Enter a valid numeric angle, second point, or option keyword

Isocircle

Creates an isometric circle in the current isometric drawing plane.

Center of circle: Specify a point
Circle radius / Diameter: Specify a distance or enter d

Note: The Isocircle option is not available if the Isometric option of SNAP is Off.

Circle Radius

Creates a circle using the specified radius.

Diameter

Creates a circle using the specified diameter.

Circle diameter: Specify a distance

Axis Endpoint 1

Defines the first axis by its two endpoints. The angle of the first axis determines the angle of the ellipse. The first axis can by either the major or the minor axis of the ellipse.

Axis endpoint 2: Specify a point (2)
Other axis distance / Rotation: Specify a distance by entering a value or locating a point (3), or enter r

Other Axis Distance (ELLIPSE, Axis Endpoint 1)

Defines the second axis using the distance from the midpoint of the first axis to the endpoint of the second axis (3).

Rotation (ELLIPSE, Axis Endpoint 1)

Creates the ellipse with the appearance of rotating a circle about the first axis.

Rotation around major axis: Specify a point (1) or enter an angle value (0-89.4)

Move the crosshairs around the center of the ellipse and pick a point. If you enter a value, the higher the value, the greater the eccentricity of the ellipse. Entering 0 defines a circular ellipse.

System Variables: PELLIPSE creates a polyline ellipse if set to 1 or a true ellipse if set to 0.
