Reconstruction of the 2016 Chilcomb Down formation | ||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | |

2. |
Copy circle 1 to its righthand intersection with the horizontal centerline. | |

3. |
Construct a circle concentric to circle 1, tangent to circle 2 at the righthand side. | |

4. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 3, pointing to the right. | |

5. |
Copy circle 1 six times, to the angular points of hexagon 4. | |

6. |
Construct the inscribed equilateral triangle of circle 1, pointing up. | |

7. |
Construct a circle, passing through the lower two angular points of hexagon 4, and tangent to the lower side of triangle 6. | |

8. |
Construct a circle concentric to circle 1, passing through the center of circle 7. | |

9. |
Construct the inscribed hexagon of circle 8, pointing down. | |

10. |
Copy circle 7 five times, to the other angular points of hexagon 9. | |

11. |
Construct the inscribed circle of triangle 6. | |

12. |
Construct the inscribed hexagon of circle 11, pointing down. | |

13. |
Construct the inscribed circle of hexagon 12. | |

14. |
Construct the inscribed circle of hexagon 4. | |

15. |
Construct the circumscribed equilateral triangle of circle 14, pointing down. | |

16. |
Copy circle 13 to the lower angular point of triangle 15. | |

17. |
Construct a circle concentric to circle 1, tangent to circle 16 at the lower side. | |

18. |
Circles 1, 5, 7, 8, 10, 13, and 17, are used for the final reconstruction. | |

19. |
Remove all parts not visible within the formation itself. | |

20. |
Colour all areas corresponding to standing... | |

21. |
...or to flattened crop, and finish the reconstruction of the 2016 Chilcomb Down formation. | |

22. |
The final result, matched with the aerial image. |
