2010 Wilton Windmill formation
|
Reconstruction of the 2010 Wilton Windmill formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Divide the righthand half of the horizontal centerline into eleven equal parts, and mark the divisions. |
| 3. |
| Construct a circle concentric to circle 1, passing through the rightmost mark 2. |
| 4. |
| Construct a circle concentric to circle 1, passing through the leftmost mark 2. |
| 5. |
| Construct the inscribed hexagon (regular six-sided polygon) of circle 4, pointing up. |
| 6. |
| Construct a circle centered at the righthand intersection of circle 4 and the horizontal centerline, tangent to the righthand side of hexagon 5. |
| 7. |
| Copy circle 6 eight times, to the middle eight marks 2. |
| 8. |
| Construct eight pairs of circles, all concentric to circle 1, each tangent at the lefthand and righthand sides of circles 7, as shown. See detail. |
|
| ||
| 9. |
| Copy circle 6 to the righthand intersection of circle 3 and the horizontal centerline. |
| 10. |
| Construct the inscribed dodecagon (regular twelve-sided polygon) of circle 3, pointing to the right. |
| 11. |
| Construct two parallel lines, tangent to circles 6 and 9 at both sides. |
| 12. |
| Repeat step 11 eleven times, relative to the other angular points of dodecagon 10, as shown. |
| 13. |
| Draw two rays of circle 1, inbetween circles 3 and 4, one horizontal to the right, one with an angle of 30° also to the right, as shown. |
| 14. |
| Divide the arc of circle 3 inbetween rays 13 into thirteen equal parts, and draw the twelve rays to the division-points similar to rays 13, as shown. |
| 15. |
| Remove all but the middle four rays 14. |
| 16. |
| Copy rays 15 eleven times, to the other eleven sectors of circle 3, as shown. |
| 17. |
| Circles 1, 3, 4 and 8, and lines 11, 12, 15 and 16, are used for the final reconstruction. |
| 18. |
| Remove all redundant parts, not visible within the formation itself. |
| 19. |
| Colour all areas corresponding to standing... |
| 20. |
| ...or to flattened crop, and finish the reconstruction of the 2010 Wilton Windmill formation. |
| 21. |
| Notice, that the central angles, associated with the arcs of the various "circular bars", are mutually different, as is shown by the dotted lines (lines 15 and 16). See also details. |
