Reconstruction of the2001 Hurn formation |
|||||

1. |
Draw a circle; this will form the outer circle of the formation. Draw the horizontal and vertical centerlines. | ||||

2. |
Construct a regular heptagon (7-sided polygon), inscribed in this circle, with one angular point at the right end of the horizontal centerline. | ||||

3. |
Draw the rays from the center of the circle to the angular points of the heptagon. | ||||

4. |
Draw the rays positioned in between rays 3, intersecting the sides of the heptagon at their midpoints. | ||||

5. |
Construct the inscribed circle of heptagon 2. It will form the inner circle of the outer ring of the formation. | ||||

6. |
Construct another heptagon, parallel to heptagon 2, inscribed in circle 5. | ||||

7. |
Construct again an inscribed circle, this time of heptagon 6. | ||||

8. |
Draw a line from intersections of this circle with rays five apart, as shown. | ||||

9. |
Construct a circle, concentric to the previous ones, tangent to line 8. It will form the outer circle of the inner rings of the formation. | ||||

10. |
Draw a line from intersections of this circle with rays three apart, as shown. | ||||

11. |
Again, construct a circle, concentric to the previous ones, tangent to line 10. It will form the middle circle of the inner rings. | ||||

12. |
Draw a line from intersections of circles 7 and 9 with rays six apart, as shown. | ||||

13. |
Construct a third circle concentric to the previous ones, tangent to line 12. It forms the inner circle of the inner rings. | ||||

14. |
Construct a circle with its center at the intersection of a ray and circle 7, and tangent to the rays next to it, as shown. (By the way, this circle has exactly the same size as circle 9). | ||||

15. |
Draw a line from the intersections of this circle with circle 5, as shown. | ||||

16. |
Copy a circle 14 with its center at the intersection of this line and the same ray (as circle 14). | ||||

17. |
Repeat this another six times for every other ray (up to a total of seven). | ||||

18. |
Leaving out all unused parts yields the reconstruction of the 2001 Hurn formation. (Black denotes flattened crop). | ||||
