Projection of Planes

1. A regular pentagon of 25 mm side has one side on the ground. Its plane is inclined at 45° to H.P. and perpendicular to the V.P. Draw its projections.

2. Draw the projection of a circle of 50 mm diameter, having its plane vertical and inclined at 30° to the V.P. Its centre is 30 mm above the H.P. and 20 mm in front of V.P.

3. A square ABCD of 50 mm side has its corner A in the H.P. , its diagonal AC inclined at 30° to the H.P. and the diagonal BD inclined at 45° to the V.P. and parallel to the H.P. Draw its projections.

4. Draw the projections of a regular hexagon of 25 mm side, having one of its sides in the H.P. and inclined at 60° to the V.P. and its surface making an angle of 45° with the H.P.

5. Draw he projections of a circle of 50 mm diameter resting in the H.P. on a point A on the circumference, its plane is inclines at 45° to H.P. and
a) The top view of the diameter AB making 30° angle with the V.P.
b) The diameter AB making 30° angle with the V.P.

6. A pentagonal plate of 45 mm side has a circular hole of 40 mm diameter in its centre. The plane stands on one of its sides on the H.P. with its plane perpendicular to V.P. and 45° inclined to the H.P. Draw the projections.

7. A circular plane 60 mm diameter rests on its rim such that its diameter 1-5 is inclined at 35° to HP and 45° to VP. Draw its front and top views.

8. A pentagonal plane of side 40 mm is resting on VP on one of its corners and the plane is inclined at 40° to the VP. Draw projections of the plane when the line joining this corner with the midpoint of opposite side is inclined at 25° to the HP.

9. Side AB of a hexagonal plane is parallel to the HP. The plane is inclined at 40° to the HP. Draw projections of the plane when the diagonal of the plane parallel to AB is inclined at 25° to the VP. Take hexagon of 40 mm side.

10. A hexagonal plane of side 30 mm is resting on HP on one of its corners and the plane is inclined at 40° to the HP. Draw projections of the plane when the line joining this corner with the opposite corner is inclined at 25° to the VP.
