Reconstruction of the 2017 Waden Hill 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 a circle centered at the top of hexagon 2, tangent to circle 1 at the lower side. | |

4. |
Copy circle 3 five times, to the other angular points of hexagon 2. | |

5. |
Construct a circle passing through the inner mutual intersections of circles 3 and 4. | |

6. |
Construct a circle concentric to circle 3, tangent to circle 5 at the lower side. | |

7. |
Copy circle 6 five times, to the centers of circles 4. | |

8. |
Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, tangent to circle 5 at the righthand side. | |

9. |
Construct a circle concentric to circle 1, tangent to circle 8 at the lefthand side. | |

10. |
Construct a circle concentric to circle 3, tangent to circle 9 at the lower side. | |

11. |
Copy circle 10 five times, to the centers of circles 4. | |

12. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 8 and its lefthand intersection with the horizontal centerline. | |

13. |
Copy circle 12 four times, to the center of circle 1 and to the lower and the upper lefthand and righthand angular points of hexagon 2. | |

14. |
Construct three pairs of parallel lines, each tangent to the outer circles 13, and all to the central one, all at both sides, as shown. | |

15. |
Circles 3, 4, 5, 6, 7, 10, and 11, hexagon 2, and lines 14, are used for the final reconstruction. | |

16. |
Remove all parts not visible within the formation itself. | |

17. |
Colour all areas corresponding to standing... | |

18. |
...or to flattened crop, and finish the reconstruction of the 2017 Waden Hill formation. | |

19. |
The final result, matched with the aerial image. |
