13 questions and parts from this paper. Open one to see it in full, then practise it on Quelpr and get it marked against the mark scheme.

1. 1(a)10 marksDraw a line AB, 95 mm long, and divide it into seven equal parts.
2. 1(b)10 marksConstruct a rectangle with sides equal to 3/7 and 6/7 of AB from part (a).
3. 220 marksFigure 1 shows a car trademark consisting of four equal circles inscribed in a larger circle of diameter 100 mm. Show the construction procedure to obtain this design.
4. 320 marksUsing the focus method, draw the curve of a hyperbola with an eccentricity of 5:3, given the distance from vertex to focal point is 25 mm and vertex to directrix is 15 mm.
5. 4(a)8 marksCopy, FULL SIZE, the given view of the circle and line ABC.
6. 4(b)12 marksPlot the locus of point P as the circle rolls for one complete revolution along the line ABC.
7. 5(a)5 marksDraw, FULL SIZE, the given plan.
8. 5(b)5 marksDraw, FULL SIZE, the given elevation.
9. 5(c)10 marksDraw, FULL SIZE, the surface development of the truncated pyramid using S-S as the seam.
10. 6(a)8 marksUsing a scale of 1:1, draw the given orthographic views.
11. 6(b)12 marksDraw an auxiliary elevation of the block projected onto the reference line XY.
12. 720 marksFigure 5 shows two orthographic views of a block. Draw an oblique projection (cabinet or cavalier) of the block, state the method used, and omit all hidden detail lines.
13. 820 marksDraw TWO convolutions of a right-hand helical spring made from a circular steel bar of diameter 10 mm, with outside diameter 70 mm and pitch 50 mm. Show all relevant constructions; hidden details are not required.
