The Polygon command creates an equilateral closed polyline. Click the dropdown to the right of the rectangle toll to access the polygon command.

When you select the Polygon command the command line will prompt you to enter the number of sides.

The following are examples of polygons.

The next prompt will ask you to specify the centre of the polygon and whether the new object is inscribed or circumscribed.

Inscribed in circle

Specifies the radius of a circle on which all vertices of the polygon lie.

Specifying the radius with your pointing device determines the rotation and size of the polygon. Specifying the radius with a value draws the bottom edge of the polygon at the current snap rotation angle.

Circumscribed about circle

Specifies the distance from the centre of the polygon to the midpoints of the edges of the polygon.

Specifying the radius with your pointing device determines the rotation and size of the polygon. Specifying the radius with a value draws the bottom edge of the polygon at the current snap rotation angle.

Edge

Defines a polygon by specifying the endpoints of the first edge.

Conclusion/Summary

The Polygon command can be used to draw any regular polygon. This command requires four inputs from the user, the number of sides, a pick point for the centre of the polygon, whether you want the polygon inscribed or circumscribed and then a pick point which determines both the radius of this imaginary circle and the orientation of the polygon. The polygon command creates a closed polyline in the shape of the required polygon.
