- a. A point 30 mm above XY line is the front view of three points P, Q and R. The top view of P is 45 mm in front of VP, the top view of Q is on XY and R is 40 mm behind VP. Draw the projections of points & state the quadrant in which the points are situated. (10 Marks)
b. The distance between the end projectors through the end points of a line AB is 60 mm. The end A is 10 mm above HP and 15 mm in front of VP. The end B is 35 mm in front of VP. The line AB appears 70 mm long in the front view. Complete the projections, Find the true length of the line and its inclinations with HP and VP. (20 Marks) - A hexagonal lamina of sides 30mm is resting on HP with one of its corners in VP and its surface inclined at an angle of 30º with VP. The diagonal passing through that corner which is in VP appears to be inclined at 40° to HP. Draw the projections of the lamina. (30 Marks)

- A square pyramid 35 mm sides of base and 60 mm axis length is suspended freely from a corner of its base. Draw the projections of the pyramid when the axis appears to be inclined to VP at 45°. (40 Marks)
- A regular pentagonal prism of height 60mm and base edge 30mm rests with its base on HP. The vertical face closest to VP is 30° to it. Draw the development of the truncated prism with its truncated surface inclined at 60° to its axis and bisecting it.
