Reconstruction of theBarbury Castle 24-05-2009 formation | |||||

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

2. |
Construct the inscribed heptagon (regular 7-sided polygon) of circle 1, pointing up. | ||||

3. |
Draw the connecting line between the upper lefthand and righthand angular points of heptagon 2. | ||||

4. |
Construct a circle centered at the lower intersection of circle 1 and the vertical centerline, tangent to line 3. | ||||

5. |
Copy circle 4 to the upper angular point of heptagon 2. | ||||

6. |
Construct a circle centered at the lower righthand angular point of heptagon 2, tangent to circle 5 at the lower side. | ||||

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

8. |
Copy circle 6 six times, to the other angular points of heptagon 2. | ||||

9. |
Construct a circle concentric to circle 5, passing through the rightmost angular point of heptagon 2. | ||||

10. |
Copy circle 9 six times, to the other angular points of heptagon 2. | ||||

11. |
Copy circle 6 fourteen times, to the outermost and next outermost sets of mutual intersections of circles 9 and 10, as shown. | ||||

12. |
Construct a circle centered at the lower intersection of circle 1 and the vertical centerline, tangent to the rightmost circle 8 at the lower lefthand side. | ||||

13. |
Copy circle 12 to the center of circle 1. | ||||

14. |
Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, tangent to circle 13 at the upper side. | ||||

15. |
Construct a circle concentric to circle 1, tangent to circle 14 at the upper side. | ||||

16. |
Copy circle 14 to the lower intersection of circle 5 and the vertical centerline, and move it (copy and delete original) to its own upper intersection with the vertical centerline. | ||||

17. |
Construct a circle concentric to circle 5, tangent to circle 16 at the upper side. | ||||

18. |
Copy circles 5 and 17 as a whole six times, to the other angular points of heptagon 2. | ||||

19. |
Circles 5, 6, 7, 8, 11, 13, 15, 17 and 18 are used for the final steps. | ||||

20. |
Remove all redundant parts not visible in the formation itself. High resolution dwf-file | ||||

21. |
Colour all areas corresponding to standing... High resolution dwf-file | ||||

22. |
...or to flattened crop, and finish the reconstruction of the Barbury Castle formation of 24-05-2009. High resolution dwf-file | ||||
