Reconstruction of the 2016 Großziethen (Germany) formation | ||

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

2. |
Copy circle 1 two times, to the righthand and upper intersections of circle 1 and the horizontal and vertical centerlines. | |

3. |
Draw the connecting line between the mutual intersections of circles 2. | |

4. |
Construct the inscribed dodecagon (regular 12-sided polygon) of circle 1, with one angular point on line 3. | |

5. |
Construct the inscribed circle of dodecagon 4. | |

6. |
Construct a circle, passing through the upper and adjacent righthand intersections of dodecagon 4 and circle 5, and tangent to line 3. | |

7. |
Copy circle 6 to the center of circle 1. | |

8. |
Draw the twelve rays of dodecagon 4, from the center to the angular points. | |

9. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 5, pointing up. | |

10. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper angular point of hexagon 9 and the lower intersection of circle 7 and the vertical centerline. | |

11. |
Copy circle 10 five times, by repeating step 10 with respect to the other angular points of hexagon 9. | |

12. |
Construct the inscribed hexagon of circle 5, pointing to the right. | |

13. |
Construct a "two-points" circle between the righthand angular point of hexagon 12 and the lefthand intersection of circle 7 and the horizontal centerline. | |

14. |
Copy circle 13 five times, by repeating step 13 with respect to the other angular points of hexagon 12. | |

15. |
Circles 1, 5, 7, 10, 11, 13, and 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 2016 Großziethen (Germany) formation. | |

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