Draw the perspective projection.

11. A rectangular prism 80 × 60 × 30 mm is placed on the ground behind the PP with the longest edges vertical and the shortest edges receding to the left an angle of 40° to the PP. The nearest vertical edge is 10 mm behind the PP and 15 mm to the left of the observer at a distance of 150mm infront of the PP. The height of the observer above the ground is 120 mm. Draw the perspective view of the prism. 

12. A square prism of base 30 × 30 cm and height 60 cm stands on ground plane with edges of the base making 50° with the picture plane. The nearest corner is 30 cm to the right of the station point and 30 cm behind PP. The station point is 50 cm above GP and 100 cm infront of PP. Draw the perspective view of the square prism.

13. Draw the perspective view of a hexagonal prism having a base with a 40 mm side and 60 mm long axis, resting on its base in the GP with a side of base parallel to and 10 mm behind the PP. The station point is 50 mm infront of PP, 75 mm above GP and lies in a CP which is 50 mm towards the right of the axis. 

14. A Hexagonal prism having 30 mm base side and 70 mm long axis is resting on its face in the GP with the axis inclined at 30° to the PP. The station point is 90 mm infront of PP, 100 mm above the GP and lies in the CP which is 70 mm towards right to the corner nearer to the PP. Draw the perspective view when the corner nearer the observer touches the PP.

15. A cylinder of diameter 30 mm and height 50 mm rests on its base on the ground with its axis 35 mm behind the PP. The eye is 25 mm to the left of the axis, 100 mm infront of the PP and 60 mm above the ground. Draw the perspective view of the cylinder.
