Q3 (a) A square lamina of 40 mm side rests on one of its sides on HP. The lamina makes 30° with HP and the side on which it rests makes 45° with VP. Draw its projections. 03
(b) Draw the development of the lateral surfaces of a square pyramid, side of base 25 mm and height 50 mm, resting with its base on HP and an edge of the base is parallel to VP. 04
(c) A hexagonal prism with side of base 30 mm and axis length 60 mm is resting on one of its base edge on HP such that its axis is inclined at 45° with HP and the side on which it is resting is inclined at 30° with VP. Draw the projections. 07

(a) Give complete classification of solids. 03
(b) A regular pentagon laminate of 30 mm each side is resting on HP on one of its sides with its surface making 45° with HP. Draw its projection when the side in HP makes an angle 30° with VP. 04
(c) A square pyramid with 40 mm side and axis 65 mm long, has its base on the HP and all the edge of base equally inclined to VP. It is cut by a section plane perpendicular to the VP and inclined at 45° to the HP. Further, it is bisecting the axis of the pyramid. Draw its sectional top view, sectional side view and true shape of the section. 07
