Reconstruction of the 1999 Barbury Castle formation The background picture is taken from this formation |
|||||
1. | ![]() | Start drawing the outer circle of the formation. | |||
2. | ![]() | Draw all centerlines spaced at 30°. | |||
3. | ![]() | Construct a (first) hexagon (regular 6-fold polygon). | |||
4. | ![]() | From the first one, construct a second inscribed hexagon, as shown. | |||
5. | ![]() | Draw the inscribed circle of this hexagon. This forms the outer border of the ring of the formation. | |||
6. | ![]() | Construct an equilateral triangle, inscribed in the outer circle, as shown. | |||
7. | ![]() | Construct three circles, centered at the cross-points of the centerlines and the inner circle and touching at the equilateral triangle, as shown. These form the inner sides of the half moon patterns. | |||
8. | ![]() | Construct again three circles, centered at the inner cross-points of the circles of the previous step, and also touching at the equilateral triangle, as shown. These circles form the outer sides of the half moon patterns. | |||
9. | ![]() | To make the path-ways, construct three circles concentric with the previous ones and going through the cross-point of the inner circle (outer border of the ring) of step 5 and a centerline, as shown. | |||
10. | ![]() | Extend three centerlines up to the outer sides of the three larger circles. They will be used for the next step. | |||
11. | ![]() | In order to make the other path-ways, draw a (small) circle, centered at the cross-point of the centerline and the smaller circle of step 8, and with a radius equal to the width of the path-way, as shown. Copy this circle to the cross-points of the centerlines and the larger circles. | |||
12. | ![]() | Construct three circles concentric to the larger circles, touching to the small circles at the inner side. | |||
13. | ![]() | The radius of the inner border of the ring (of course concentric with the outer border) is determined by the cross-points of the larger and the smaller circles (steps 7 and 8) at the outmost side, as shown. | |||
14. | ![]() | Now, all circles have been derived to reconstruct the 1999 Barbury Castle formation. | |||
15. | ![]() | The final reconstruction appears after removing all superfluous parts. | |||
