2011 Fonthill Down formation
|
Reconstruction of the 2011 Fonthill Down formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct the inscribed hexagon of circle 1, pointing to the right. |
| 4. |
| Divide the horizontal centerline of circle 1 into five equal parts. |
| 5. |
| Construct a circle centered at the leftmost division node 4, tangent to the lefthand side of hexagon 2. |
| 6. |
| Construct a circle centered at the righthand intersection, and passing through the lefthand intersection of circle 5 with the horizontal centerline. |
| 7. |
| Construct a circle concentric to circle 1, passing through the center of circle 6. |
| 8. |
| Construct the inscribed hexagon of circle 7, pointing to the right. |
| 9. |
| Copy circle 6 five times, to the other angular points of hexagon 8. |
| 10. |
| Construct a circle concentric to circle 6, tangent to both lefthand sides of hexagon 3. |
| 11. |
| Copy circle 10 five times, to the centers of circles 9. |
| 12. |
| Construct a circle concentric to circle 1, tangent to circle 6 at the righthand side. |
| 13. |
| Copy circle 12 to the lower intersection of circle 1 and the vertical centerline. |
| 14. |
| Construct a circle concentric to circle 1, tangent to circle 13 at the lower side. |
| 15. |
| Construct a circle centered at the righthand intersection of circle 10 and the horizontal centerline, passing through the righthand intersection of the leftmost two circles 9. |
| 16. |
| Copy circle 15 to the lower intersection of circle 14 and the vertical centerline, and move this circle (copy and delete original) to its own lefthand intersection with circle 14. |
| 17. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 16 and its righthand intersection with circle 14. |
| 18. |
| Copy circle 17 to the center of circle 16. |
| 19. |
| Circles 1, 6, 9, 10, 11, 16 and 18, are used for the final reconstruction. |
| 20. |
| Remove all parts not visible within the formation itself. |
| 21. |
| Colour all areas corresponding to standing... |
| 22. |
| ...or to flattened crop, and finish the reconstruction of the 2011 Fonthill Down formation. |
| 23. |
| The final result, matched with the aerial image. |
