Reconstruction of the 2015 Blackhorse Lane 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 down. |
| 3. |
| Draw the ray of hexagon 2, from the center of circle 1 to its lower lefthand angular point. |
| 4. |
| Draw the ray of hexagon 2, from the center of circle 1 to its lower righthand angular point. |
| 5. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its lower intersection with the vertical centerline. |
| 6. |
| Construct two "two-points" circles, between the center of circle 5 and each of its intersections with the vertical centerline. |
| 7. |
| Construct three circles concentric to circle 1, passing through the centers of circles 5 and 6. |
| 8. |
| Copy circles 7 to the lower intersection of circle 1 and the vertical centerline. |
| 9. |
| Draw three parallel lines, from the intersections of circles 7 and line 3 to the intersections of circles 8 and the lower righthand side of hexagon 2. |
| 10. |
| Draw three parallel lines, from the intersections of circles 7 and line 4 to the intersections of circles 8 and the lower lefthand side of hexagon 2. |
| 11. |
| Draw a line from the center of circle 1 to its lower intersection with the vertical centerline. |
| 12. |
| Draw three vertical lines from the intersections of lines 9 and line 3 to the intersections of lines 10 and the lower lefthand side of hexagon 2. |
| 13. |
| Draw three vertical lines from the intersections of lines 10 and line 4 to the intersections of lines 9 and the lower righthand side of hexagon 2. |
| 14. |
| Draw a line from the center of circle 1 to the intersection of the upper line 9 and the middle line 10. |
| 15. |
| Construct a circle centered at the intersection of the upper line 10 and line 14, tangent to the innermost circle 7 at the lower righthand side. |
| 16. |
| Copy circle 15 to the righthand intersection of circle 1 and the horizontal centerline. |
| 17. |
| Construct a circle concentric to circle 1, tangent to circle 16 at the righthand side. |
| 18. |
| Construct a "two-points" circle between the center of circle 15 and its lower intersection with line 14. |
| 19. |
| Copy circle 18 to the lower righthand angular point of hexagon 2. |
| 20. |
| Copy circle 18 to the center of circle 1. |
| 21. |
| Draw a line parallel to line 4, tangent to circles 19 and 20 at the lower lefthand sides. |
| 22. |
| Copy circle 18 to the lower angular point of hexagon 2. |
| 23. |
| Draw a line parallel to the lower righthand side of hexagon 2, tangent to circles 19 and 22 at the upper lefthand sides. |
| 24. |
| Circles 1 and 17, hexagon 2, and lines 3, 4, 9, 10, 11, 12, 13, 21, and 23, are used for the final reconstruction. |
| 25. |
| Remove all parts not visible within the formation itself. |
| 26. |
| Colour all areas corresponding to standing... |
| 27. |
| ...or to flattened crop, and finish the reconstruction of the 2015 Blackhorse Lane formation. |
| 28. |
| The final result, matched with the aerial image. |
