Method
•Construct two concentric circles, one of which is twice the radius of the other
•Divide the circles into six radiant parts, and draw concentric mouldings
•Draw six circles centred on the moulding, and then draw mouldings concentric to the smaller circles
•Terminate all curved lines at their intersection points
Hexafoil construction
Step 1: Draw a vertical line and a horizontal line intersecting at point A near the centre of the page
Step 2: Centre compasses at A and draw a circle with radius 50mm
Step 3: Keeping the same radius, centre compasses at B and scribe arc B A C
Step 4: Draw a circle centred at A with radius A C
Step 5: Keeping the same radius, draw two arcs at each point C D E and F to intersect with the circle AC
Step 6: Draw construction lines through the centre point, dividing the circle into twelve parts
Step 7: Draw a moulding with radius 90mm
Step 8: Draw a moulding with radius 60mm and mark off six points around it
Step 9: Draw six circles centred around the inner circle so that they are all touching each other
Step 10: Draw mouldings with radius 25mm
Step 11: Terminate all circles at their intersection with the inner circle
Step 12: Remove the inner circle
Step 13: Clean up construction lines and darken outlines
