N-GON allows you to create a polygon with sides of equal
length, consisting of line entities.

Enter the desired number of sides in the polygon (from 3 
to 100) and press <Enter>, or accept the default value in
parentheses by pressing <Enter>.

Enter a rotation angle (in degrees) for the base of the
polygon and press <Enter>, or accept the default value in
parentheses by pressing <Enter>. This angle is defined so 
the side of the polygon is horizontal with an angle of
zero degrees. Positive angle values result in a counter-
clockwise rotation of the polygon about its center.

Enter radius value.

Indicate the radius by choosing from the following 
options:

CORNER - to indicate the radius from a vertex (corner) of
         the polygon.

FLAT   - to indicate the radius inscribed within the 
         polygon (flat).


The center of the polygon is determined as a point
equidistant from all vertices.
