The document provides instructions for drawing two types of scotia curves used in stonemasonry: quadrants and elliptical. For quadrants, the steps include laying out a grid, finding center points, scribing curves, and adding fillets. For elliptical curves, the steps involve laying out radiating lines from a center point using proportional measurements and then drawing the curve connecting the points.

1. Drawing a scotia (Quadrants and elliptical) _ Stonemasonry technical skills at SkillsTech Australia

3. Step 1: Draw a grid of squares and mark out curve centres and confluence Quadrants

4. Step 2: D raw the first quadrant to the confluence point Quadrants

5. Step 3: Draw the second quadrant, meeting the first quadrant at the confluence point Quadrants

6. Step 4: Add fillets at top and bottom Quadrants

7. Step 5: Clean up construction lines and draw outlines Quadrants

8. Step 6: Draw a horizontal centre line, and a line at 60 0 to it Elliptical

9. Step 7: Step off three times up and down from the centre line Elliptical

10. Step 8: Step off three times horizontally from the top and bottom, and mark the first radiating intersection point Elliptical

11. Step 9: Step off an equal amount to mark the second radiating point Elliptical

12. Step 10: Draw the first set of radiating intersection lines Elliptical
