il) A point P is 40 mm above HP. 60mm behind VP and 50mm In front of right PP. Draw the projections of point P. (2 Mrk)
(b) Draw the projections of a straight line PQ 100mm long, inclined at 45 to HP and 30 to VP. The end P is In HP and the end Q is in VP. (is Mark*)
2. (a) i) A point lying 20 mm above the XY line represents the front views of two points
E and F. The top -/lew of E Is 35mm above XY and the top view of F is 40 mm below XY. Draw the projections of the two points. (3 Marks)
ii) A point touches all the three principal planes of projections. Draw its projections. (2 Marks)
(b) The point B of the line AB is on HP and the top view ab of the line makes an angle of 30 with the line of intersection of VP & HP. ab being 80mm. The point A lies on the VP and 50mm above HP. Draw the top and front views of the line and obtain the truse length. (is Mark*)
3. A hexagonal lamina of 30 mm sides rests on HP with one of its corners touching VP and its surface is inclined at 45 to VP. One of the edges is inclined to HP at 30, Draw the projections. (20 Marks)
4. Draw the top, front and left views of a hexagonal pyramid of sides of base 30mm and height 60mm resting on one of its triangular faces on HP and axis parallel to VP. The apex of the pyramid lies on the left side. (20 Marks)
