AUTOCAD TUTORIAL: Chapter 2 Introduction Of 2D Drawing Tool > polygon Tool

AutoCAD has a wide library of commands. There are many commands which used to drawing any type of drawing. Today i am going to tell you about various method to drawing polygon in AutoCAD.

Polygon:

Short key : POL
Polygon is the shape which has more than two sides and each side is equal length. There are two methods to draw polygon in AutoCAD.

1. With the reference of a circle:

This method is used when we know the radius of the polygon. In this method first draw a circle whose radius is same as the polygon radius and then follow this method.
Select polygon tool from quick access toolbar or by short key POL enter.
Now enter number of sides of the polygon.
After it specified the center point of polygon by clicking the left click of mouse at the center of the circle.
Now press I enter to draw the polygon inside the circle or press C to draw the polygon at circumscribed(outside) to the circle.
Now enter the radius of the polygon.
Now delete the circle.
Example:
Draw a polygon who has eight sides and whose radius is 6.
Solution:

8 enter
Select the center of the circle.
Press I for inside the circle and C for outside the circle.
6 enter 

2. With the reference of a line:

Now enter number of sides of the polygon.
Now press E enter to select the edge option which allow to draw the polygon with reference to side length.
Now select the starting and ending points of line.
Example:
Draw a circle who has 6 sides and each length of each side is 2.
solution:

First draw a line of length 2
POL enter
6 enter
E enter
Select first point of line by clicking the mouse.
Select end point of the line by clinking the mouse.
