Candidates were expected to:

1. draw the given elevation of the cone and cylinder;
2. draw the semi-circle of the cylinder on the elevation;
3. draw horizontal lines from the divisions on the semi-circle to side of the cone;
4. project downward from the front elevation to the plan;
5. draw the semi-circle on the cylinder and divide into 6 equal parts;
6. draw horizontal lines from the divisions on the semi-circle into the base circle;
7. project down from the side of the cone to the centre line of the base circle on the plan;
8. draw circles with section radii to locate points of intersection of the plan;
9. complete the plan, curves and horizontal lines;
10. project up from the plan and draw curve of intersection.

The solution is shown below

   (B)       Development of Cylinder

            Candidates were expected to:

1. layout the circumference of the cylinder;
2. draw perpendicular lines on the circumference;
3. transfer dimensions from the cylinder on the elevation to locate the points on the perpendicular lines on the circumference.

The solution is shown below
