Reconstruction of the Ackling Dyke 21-06-2020 formation | |||||
1. | ![]() | Draw a circle. Draw the horizontal and vertical centerlines. | |||
2. | ![]() | Construct the inscribed regular 14-sided polygon of circle 1, pointing up. | |||
3. | ![]() | Draw the fourteen rays of polygon 2, from the center to the angular points. Number these rays clockwise 1 - 14, starting at the top. | |||
4. | ![]() | Draw the connecting line between the righthand intersection of circle 1 and the horizontal centerline, and the intersection of circle 1 and ray 3 nr. 1. | |||
5. | ![]() | Construct a circle concentric to circle 1, tangent to line 4. | |||
6. | ![]() | Repeat step 4 thirteen times, with respect to the other rays 3 and corresponding positions, as shown. | |||
7. | ![]() | Construct a circle centered at the intersection of circle 5 and ray 3 nr. 2, passing through the intersection of line 4 and ray 3 nr. 2. | |||
8. | ![]() | Copy circle 7 to the upper intersection of circle 1 and the vertical centerline. | |||
9. | ![]() | Construct a circle concentric to circle 1, tangent to circle 8 at the lower side. | |||
10. | ![]() | Draw the connecting line between the righthand intersection of circle 1 and the horizontal centerline, and the intersection of circle 9 and ray 3 nr. 14. | |||
11. | ![]() | Construct a circle concentric to circle 1, tangent to line 10. | |||
12. | ![]() | Draw the connecting line between the intersections of circle 11 with rays 3 nrs. 1 and 7. | |||
13. | ![]() | Repeat step 12 six times, with respect to the pairs of rays 3 nrs. 3 and 9, 5 and 11, 7 and 13, 9 and 1, 11 and 3, and 13 and 5. | |||
14. | ![]() | Circles 1, 5, and 9, and lines 3, 4, 6, 12, and 13, are used for the final reconstruction. | |||
15. | ![]() | Remove all parts not visible within the formation itself. pdf-file | |||
16. | ![]() | Colour all areas corresponding to standing... pdf-file | |||
17. | ![]() | ...or to flattened crop, and finish the reconstruction of the Ackling Dyke formation of 21-06-2020. pdf-file | |||
