ELLIPSE allows you to create an elliptical arc by defining
the length and orientation of the major and minor axes, 
and the start, end, and center points of the entity.

Define the length of the semi-major axis. Enter a value 
for the length of the semi-major axis and press <Enter>, 
or accept the default value by pressing <Enter>.

Define the length of the semi-minor axis.

Enter a value for the length of the semi-minor axis and
press <Enter>, or accept the default value by pressing
<Enter>.

Enter a value for the desired angle between the major axis
and the construction view x axis and press <Enter>, or
accept the default value by pressing <Enter>.

Enter a start angle for the ellipse. 

Define the desired start point by entering a value for the
start angle and pressing <Enter>, or accept the default
value by pressing <Enter>.

You are prompted to enter an end angle for the ellipse.

Define the desired end point by entering a value for the 
end angle and pressing <Enter>, or accept the default 
value by pressing <Enter>.

Indicate a position for the center of the ellipse, using a
Position Menu option.

The center is projected to the current construction plane,
and the elliptical arc is created in the current
construction view, at the current depth. If the start and
end angles are the same, the entire ellipse is created.

To create another elliptical arc with the same
specifications (i.e., major and minor axis lengths, start
and end angles), indicate another center position.
