Reconstruction of the 2012 Windmill Hill (2) formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular six-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct the inscribed circle of hexagon 2. |
| 4. |
| Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, tangent to circle 1 at the lefthand side. Move this circle (copy and delete original) to its own righthand intersection with the horizontal centerline. |
| 5. |
| Construct a circle centered at the righthand intersection of circle 3 and the horizontal centerline, tangent to circle 1 at the righthand side. |
| 6. |
| Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, tangent to circle 5 at the lefthand side. |
| 7. |
| Construct a circle concentric to circle 4, tangent to circle 6 at the righthand side. |
| 8. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the lefthand intersection of circle 1 and the righthand intersection of circle 4 both with the horizontal centerline. |
| 9. |
| Copy circle 6 to the righthand intersection of circle 8 and the horizontal centerline, and move this circle to its own corresponding intersection. |
| 10. |
| Construct a circle concentric to circle 8, passing through the center of circle 9. |
| 11. |
| Construct a circle concentric to circle 8, tangent to circle 9 at the righthand side. |
| 12. |
| Copy circle 11 to its righthand intersection with the horizontal centerline, and move this circle to its own corresponding intersection. |
| 13. |
| Construct a circle concentric to circle 12, tangent to circle 10 at the righthand side. |
| 14. |
| Construct a circle concentric to circle 12, tangent to circle 8 at the righthand side. |
| 15. |
| Construct a "two-points" circle between the righthand intersections of circles 1 and 14 with the horizontal centerline. |
| 16. |
| Construct a circle concentric to circle 15, tangent to circle 6 at the lefthand side. |
| 17. |
| Copy circle 6 to the righthand intersection of circle 16 and the horizontal centerline. |
| 18. |
| Construct a circle concentric to circle 15, tangent to circle 17 at the righthand side. |
| 19. |
| Copy circle 1 to the righthand intersection of circle 14, and move this circle to its own lefthand intersection, both with the horizontal centerline. |
| 20. |
| Copy circle 1 to the righthand intersection of circle 4 and the horizontal centerline, and move this circle to its own corresponding intersection. |
| 21. |
| Construct a circle concentric to circle 20, tangent to circle 7 at the righthand side. |
| 22. |
| Copy circle 6 to the lefthand intersection of circle 21 and the horizontal centerline. |
| 23. |
| Construct a circle concentric to circle 20, tangent to circle 22 at the lefthand side. |
| 24. |
| Copy circles 21 and 23 to the righthand intersection of circle 20 and the horizontal centerline. |
| 25. |
| Construct two circles concentric to circle 1, tangent to circles 24 at the righthand sides. |
| 26. |
| Copy circles 4, 7, 8, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, and 23, as a whole, while mirroring with respect to the vertical centerline. |
| 27. |
| Circles 1, 3, 4, 7, 8, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 23, 25 and 26, are used for the final reconstruction. |
| 28. |
| Remove all parts not visible within the formation itself. |
| 29. |
| Colour all areas corresponding to standing... |
| 30. |
| ...or to flattened crop, and finish the reconstruction of the 2012 Windmill Hill (2) formation. |
| 31. |
| The final result, matched with the aerial image. |
