Vertex editing allows you to change the shape of an existing regular polygon, and to add or delete vertices. After performing vertex editing, the resulting entity will no longer be a regular polygon. For information on vertex editing, see the chapter titled "Reshaping Entities," which begins on page 299. To draw a regular polygon by entering its center and edge points 1 On the Draw menu, click Polygon, Center, Edge, or click the Center-Edge Polygon button on the All-In-One toolbar. 2 (optional) Click or enter the different number of sides in the Number of Segments box on the edit bar and press ENTER. 3 (optional) Click Inscribe or Circumscribe from the drop-down list box on the edit bar to determine if the polygon is inscribed in the reference circle or circumscribed around it. This setting determines the meaning of the points you enter in the following steps. 4 Click the centerpoint of the regular polygon. A small diamond marker marks the point and a rubber-band polygon appears, moving with the pointer. 5 (optional) Press and hold CTRL while you click the point in the next step to reverse the points. 6 Click the corner point for the polygon if Inscribe appears on the edit bar, or enter a midpoint for a side of the polygon if Circumscribe appears. If you are holding CTRL, the corner or side point is switched with the centerpoint. To draw a regular polygon by entering opposite corners or sides 1 On the Draw menu, click Polygon, Regular: Edge, Opposite, or click the Edge-Opposite Polygon button on the All-In-One toolbar. 2 (optional) Click or enter a different number of sides in the Number of Segments box on the edit bar and press ENTER. 148 | Chapter 12 Polylines, Polygons, & Curves
