The Polygon command enables you to create an Inscribed or Circumscribed polygon (depending on the option you select in the Mode drop-down list) based on
Radius
Number of Edges
Orientation Angle (measured counterclockwise starting from the X-axis).
Enter each value into the corresponding box; press TAB to confirm and move to the other box. Press ENTER to create the polygon.
When working in the model (three-dimensional) environment, the resulting entities are created on the Work Plane.
