The document provides step-by-step instructions for constructing a hexafoil shape using geometric principles. It describes drawing concentric circles divided into six sections and then drawing additional concentric circles centered on the divisions to form the intricate hexafoil pattern. Thirteen steps are outlined to first lay guidelines and construction lines, then draw the nested circles and terminating curves to produce the finished hexafoil shape.

1. Drawing a hexafoil _ Stonemasonry technical skills at SkillsTech Australia

3. Step 1: Draw a vertical line and a horizontal line intersecting at point A near the centre of the page

4. Step 2: Centre compasses at A and draw a circle with radius 50mm

5. Step 3: Keeping the same radius, centre compasses at B and scribe arc B A C

6. Step 4: Draw a circle centred at A with radius A C

7. Step 5: Keeping the same radius, draw two arcs at each point C D E and F to intersect with the circle AC

8. Step 6: Draw construction lines through the centre point, dividing the circle into twelve parts

9. Step 7: Draw a moulding with radius 90mm

10. Step 8: Draw a moulding with radius 60mm and mark off six points around it

11. Step 9: Draw six circles centred around the inner circle so that they are all touching each other

12. Step 10: Draw mouldings with radius 25mm

13. Step 11: Terminate all circles at their intersection with the inner circle

14. Step 12: Remove the inner circle

15. Step 13: Clean up construction lines and darken outlines
