Learning Objectives

After completing this lesson, you will be able to:

1. Draw an Inscribed or Circumscribed Polygon

2. Create an Ellipse using two different methods

3. Define an Elliptical Arc

4. Create Donuts

5. Define a Location with a Point

6. Select various Point Styles

7. Use 3 new Object Snap modes

Polygon

A polygon is an object with multiple edges (flat 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 center and a radius or the edge length. The radius size can be specified Inscribed) or Circumscribed.

Center, Radius Method

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

   • Ribbon = Home tab / Draw panel ? /

   • Keyboard = POL

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

   • _polygon Enter number of sides <4>: type number of sides < enter>

   • Specify center of polygon or [Edge]: specify the center location (P1)

   • Enter an option [Inscribed in circle/Circumscribed about circle]: type I or C

   • Specify radius of circle: type radius or locate with cursor. (P2)

Note	The dashed circle is shown only as a reference to help you visualize the difference between Inscribed and Circumscribed. Notice that the radius is the same (2") but the Polygons are different sizes. Selecting Inscribed or Circumscribed is important.
