2. Define the major axis by clicking the endpoint of the axis, which is a point on the ellipse. You can also enter a coordinate into the command line or enter an angle and major radius in the format `@50<30` where 50 is the major radius and 30 is the ellipse angle.
3. Define the endpoint of the minor axis which is also a point on the ellipse.

## 20.2. Ellipse Arcs

CAD Toolbar:

Menu:

    Draw - Ellipse - Ellipse Arc

Command:

    ellipsearc

Draws ellipse arcs with a given center, major and minor axis and start and end angles.

Procedure:

1. Set the center of the ellipse using the mouse or enter a coordinate in the command line.
2. Define the major axis by clicking the endpoint of the axis, which is a point on the ellipse. You can also enter a coordinate into the command line or enter an angle and major radius in the format `@50<30` where 50 is the major radius and 30 is the ellipse angle.
3. Define the endpoint of the minor axis which is also a point on the ellipse or enter the length of the minor axis.
4. Set the start angle with the mouse or by entering a coordinate or the angle amount in the command line.
5. Set the end angle the same way as the start angle.
