Solve any one question from Q.1 & Q.2
1 A line PQ 90 mm long, is inclined to H.P and V.P at 34° and 30° respectively. Draw the projections if point P is 25 mm above H.P. and point Q is 20 mm in front of V.P. Also locate the traces.
12 M

2 A circular plate of diameter 60 mm is resting on H.P. It is then inclined to H.P. so that the point opposite to resting points is 40 mm above H.P. Draw the projections if the plan of diameter line passing through resting point makes 35° XY. Find inclinations made by the plate with reference planes..
