  Specifies the radius of a circle:

  After entering the radius of the circle, AutoCAD2013 assumes a radius of an input value, the circle center of the circle center of the polygon, and draw circle inscribed in the regular polygon in accordance with a specified number of sides.

  2.If you choose to perform "circumscribed circle (C)" option, AutoCAD2013 same tips:

  Specifies the radius of a circle:

  After entering the radius of the circle, AutoCAD2013 assumes a radius of an input value, the circle center of the circle center of the polygon, and drawn outside the circle inscribed in accordance with the number of sides of the regular polygon specified.

  (2) the edge (E)

  The two end points of a regular polygon rendering a polygon edge.Implementation of this option, AutoCAD2013 in turn prompt:

  Specify the first endpoint of edge:

  Specified edge of the second endpoint:

  After the user sequentially determines the end points of the edge, AutoCAD2013 to these two points as two end points of a regular polygon on one side, and drawn by the specified number of sides of a regular polygon.

  NOTE: The "side when (E) a regular polygon rendering option, AutoCAD2013 always to the second endpoint, the counterclockwise direction from a first end of a regular polygon drawn specified.

  For example, two points are known, if the two points as the sides of a regular hexagon two endpoints draw a regular hexagon, the different points respectively as a first, a second end, will be hexagonal different positions, as shown:

  Draw a regular polygon:

  1.Select the inverted triangle button to the right of the rectangle on the AutoCAD2013 toolbar, the pop-up menu, select "Polygon".Or execute commands POLYGON.

  2.Input side: 8

  3.Specified regular polygon center point or [(E)] :( in place in the drawing window, click the left mouse button with the specified point)

  4. Enter an option [access to the circle (I) / and the circumscribed circle (C) within a]: I

  5.Specify radius of circle: 500 (for an octagon, with a leg length equal to the corresponding radius of the circumscribed circle)
