1).Draw the projection of a circle of 70 mm diameter resting on H.P. on a point A of the circumference. Plane is inclined to H.P. such that the plan of it is an ellipse of minor axis 40 mm. The plan of the diameter, through the point A, is making an angle of 45° with the V.P. measure the angle of the plane with the H.P.
2).A regular hexagonal plate 30 mm side is resting on one of its corners in H.P. The diagonal through that corner is inclined at 40 ̊ to H.P. and diagonal is inclined at 30 ̊ to V.P. Draw the projection of Hexagonal plate.
3).A regular pentagonal plate, of 35 mm sides, has one of its corners in H.P. The plane of the pentagon is inclined at 30° to the H.P. The side of the pentagon which is opposite to the corner, which is on H.P. is inclined at 45° to V.P. Draw the projections of the plate.
4). A square plate having size 40 mm, is resting on V.P. with one of its corner . The plane is inclined to V.P. by 40°. The diagonal passing through the point which is on V.P. ,is inclined at 30° to the H.P. Draw its projection.
5). A semicircular plate of 80mm diameter has its straight edge in the VP and inclined at 45 to HP. The surface of the plate makes an angle of 30 with the VP. Draw its projections.
6).A thin rectangular plate of 60 × 30 mm has its shorter side in the VP and inclined at 30° to the HP. Project top view, if its front view is a square of 30 mm long side.
7).A circular lamina of 60 mm diameter is resting on H.P. on a point A of the circumference, with its plane inclined at 45° to H.P. and the plan of diameter through point A makes 30° with V.P. Draw projections of the lamina.
