Reconstruction of the Fox 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 | |||
