Answer any one question from Q1 and Q2
1 The point P of 75 mm long line PQ is 25 mm above HP while its end point Q is 20 mm in front of VP. Its elevation makes 40° with HP while, the projector distance between the end points of line is 60mm. Draw the projections of a line and find the inclinations made by it with HP and VP. Also, locate the traces of line.

2 A hexagonal plate, base side 40 mm, is resting in HP on one of its corner with its side parallel to V.P. Then, its surface is inclined to HP at 40°. Draw the projections, if it's top view line passing through resting corner and its opposite corner, is inclined to VP at an angle of 35°. Also find the inclination made by the plate with VP.

Answer any one question from Q3 and Q4
3 A cone of base diameter 60mm and axis height 80 mm is resting in HP on one of its base circumference point. Then, its base surface is inclined to HP at 60°. Draw the projections, if its axis is inclined to VP at 35°, with its apex away from the observer.
