A-CAD COMMAND "POLYGON"

POLYGON:

Polygon Command is the command used to form many irregular terms . 

Inscribed in Circle
Command: pol
Enter number of sides (-): (specify how many sides you want)

Enter an option [Inscribed in circle / a circumscribed about circle] (I): (Select I to determine Inscribed in circle)

Specify radius of circle: (Determine the magnitude of the radius)

In this method, you must determine the center and radius polyton. What is meant by the radius is the distance the center of the polygon corners.

Circumscribed About Circle
Command: pol
Enter number of sides (-): (specify how many sides you want)

Enter an option [Inscribed in circle / a circumscribed about circle] (I): (Select C to determine the circle circumscribed about)

Specify radius of circle: (Determine the magnitude of the radius)

This method is similar to the Inscribed in Circle, but what distinguishes his fingers is the distance between the center of the mid-sides of the polygon.

Edge
Command: pol
Enter number of sides (-): (specify how many sides you want)
Specify center of polygon or [edge]: (choose e to specify edge options)
Specify first endpoint of edge: (Specify the starting point of the polygon)
Specify second endpoint of edge: (specify the next point of the polygon)

In this method, you must specify two points on one side of the polygon, without specifying the polygon center.
