Regular (equal-sided) polygon
Use the Regular Polygon tool to create single-line closed polygons in which all sides of the polygon are the same length. The Push/Pull mode is available in 3D views for instantly extruding the polygon after creation.
 
 
| Mode | Description | 
| Inscribed 
 | Creates a polygon by drawing its radius to a corner | 
| Circumscribed 
 | Creates a polygon by drawing a radius to the mid-point of a side | 
| Edge 
 | Creates a polygon by drawing one of its sides | 
| Push/Pull (3D views only) 
 | Instantly extrudes the polygon after creation; see Push/Pull mode of planar tools | 
| Push/Pull Combine (available with Push/Pull mode) 
 | When the shape to be extruded is drawn on the face of a solid object, combines the two objects into a single solid addition or solid subtraction; when this submode is disabled, the new extrude remains a separate object, and the existing solid object remains unchanged | 
| Number of Sides | Sets how many sides the polygon has (from 3 to 4000) | 
Press and hold the Option (Mac) or Ctrl (Windows) key while drawing to toggle between circumscribed and inscribed modes.
