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.
