Reconstruction of the1999 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. | ||||
