Reconstruction of theFox Ground Down 30-05-2015 formation | |||||

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

2. |
Construct the inscribed regular 15-sided polygon of circle 1, pointing down. | ||||

3. |
Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, tangent to the upper side of polygon 2. | ||||

4. |
Copy circle 3 to the center of circle 1. | ||||

5. |
Divide the part of the horizontal centerline between the righthand intersections with circles 4 and 1 into fifteen equal parts. Number the nodes from left to right 1 - 14. | ||||

6. |
Construct a circle concentric to circle 1, passing through node 5 nr. 14. | ||||

7. |
Construct a circle centered at the lefthand intersection of circle 6 and the horizontal centerline, tangent to circle 4 at the righthand side. | ||||

8. |
Construct a circle concentric to circle 7, passing through node 5 nr. 1. | ||||

9. |
Copy circles 7 and 8 three times, to the other intersections of circle 6 and the horizontal and vertical centerlines. | ||||

10. |
Construct a circle concentric to circle 1, passing through node 5 nr. 13. | ||||

11. |
Construct a circle concentric to circle 1, passing through node 5 nr. 12. | ||||

12. |
Copy circles 10 and 11 four times, to the centers of circles 7 and 9. | ||||

13. |
Construct three circles concentric to circle 1, passing through nodes 5 nrs. 9, 10 and 11. | ||||

14. |
Construct four circles concentric to circle 1, passing through nodes 5 nrs. 1, 2, 3 and 4. | ||||

15. |
For clarity reasons, some of the results of previous steps are removed temporarily.Draw two parallel lines, tangent to circles 3 and 4 at both sides, and extend these lines downto circle 1. | ||||

16. |
Draw eight lines parallel to the vertical centerline, tangent to circles 14 at both sides, and extend these lines upto and downto circle 1. | ||||

17. |
Repeat steps 15 and 16, with respect to the horizontal centerline, as shown. | ||||

18. |
Circles 1, 6, 7, 8, 9, 10, 11, 12, 13, and 14, and lines 15, 16, and 17, are used for the final reconstruction. | ||||

19. |
Remove all parts not visible within the formation itself. pdf-file | ||||

20. |
Colour all areas corresponding to standing... pdf-file | ||||

21. |
...or to flattened crop, and finish the reconstruction of the Fox Ground Down formation of 30-05-2015. pdf-file | ||||
