LEARNING OBJECTIVES

After completing this lesson, you will be able to:

1. Draw an Inscribed and Circumscribed Polygon.

2. Create an Ellipse using two different methods.

3. Draw an object called Donut.

4. Define a Point location.

5. Select various Point Styles.

6. Use 3 new Object Snap modes.

POLYGON

A polygon is an object with multiple sides of equal length. You may specify from 3 to 1024 sides. A polygon appears to be multiple lines, but, in fact, it is one object. You can specify the edge length or the center and a radius. The radius can be drawn inside (Inscribed) an imaginary circle or outside (Circumscribed) an imaginary circle.

CENTER / RADIUS METHOD

1. Select the Polygon command using one of the following:

   • TYPING = POL

   • PULLDOWN = DRAW / POLYGON

   • TOOLBAR = DRAW

1. The following prompts will appear on the command line:

   _polygon Enter number of sides <4>: type number of sides
   Specify center of polygon or [Edge]: specify the center location
   Enter an option [Inscribed in circle/Circumscribed about circle]: type I or C
   Specify radius of circle: type radius or locate with cursor.

EDGE METHOD

1. Select the Polygon command using one of the following:

   • TYPING = POL

   • PULLDOWN = DRAW / POLYGON

   • TOOLBAR = DRAW

1. The following prompts will appear on the command line:

   _polygon Enter number of sides <4>: type number of sides
   Specify center of polygon or [Edge]: type E
   Specify first endpoint of edge: place first endpoint of edge (P1)
   Specify second endpoint of edge:
