16. |
Construct the "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circles 13 and 15 with the vertical centerline. | |

17. |
Copy circle 16 to the top of square 2, and move this circle (copy and delete original) to its own lower intersection with the vertical centerline. | |

18. |
Construct a circle concentric to circle 1, tangent to circle 17 at the lower side. | |

19. |
Copy circles 13 and 15 to the center of circle 17. See detail. | |

20. |
Copy circles 13 and 15 three more times, to the corresponding positions with respect to the other angular points of square 2. | |

21. |
Construct the "two-points" circle between the center of circle 16 and its lower intersection with the vertical centerline. | |

22. |
Copy circle 21 to the top of square 4. | |

23. |
Construct a circle concentric to circle 1, tangent to circle 22 at the lower side. See detail. | |

24. |
Construct the "two-points" circle between the center of circle 22 and its lower intersection with the vertical centerline. | |

25. |
Copy circle 24 four times, to the angular points of square 4. See detail. | |

26. |
Construct two pairs of parallel lines, parallel to the horizontal and vertical centerlines respectively, tangent to circles 25, all at both sides. See detail. | |

27. |
Circles 1, 3, 5, 7, 9, 11, 13, 15, 18, 19, 20, and 23, and lines 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 2017 Space Science Centre formation. | |

31. |
The final result, matched with the aerial image. |
