What is meant by orthographic projection? 2. Distinguish between first angle projection and third angle projection. 3. State the practical application of development of surfaces. 4. Just like cones and cylinders, spheres can also be developed accurately (True/false). 5. Define isometric axes. 6. What is the purpose of drawing the isometric projection of an object? 7. What is the shape of the perspective view of a circle lying on the ground? 8. Define the term vanishing point. 9. Give the graphical conventions representing the following (a) Brick work (b) Concrete 10. Define rise and tread in the case of steps. PART – B Answer ALL the Questions (5 x 12 = 60) 11. Fig. 1 shows the pictorial view of the guide bracket for a horizontal spindle. Draw the three orthographic views. (or) 12. Draw the front view, top view, and right side view of the object shown in fig.2. 13. A cone of base diameter 60mm and altitude 70mm rests in its base on the HP. It is cut by a plane perpendicular to both HP and VP and passing through the cone 10mm to the left of the axis. Draw the development of the lateral surface of the right portion of the cut cone. 14. A horizontal cylinder of diameter 40mm penetrates into a vertical cylinder of diameter 60mm. The axis of the cylinders intersects at right angles. Draw the curves of intersection when the axis of the horizontal cylinder is parallel to the VP. 15. A pentagonal pyramid, 25 mm edge of base and 60 mm height stands on HP such that an edge of the base is perpendicular to VP and nearer to it. A sectional plane perpendicular to VP and inclined at 30 to HP cuts the pyramid passing through a point on the axis at a height of 35 mm from the base. Draw the isometric view of the truncated pyramid, showing the cut surface. (or) 16. A cylinder of 60mm diameter and 70mm height stands on HP-A section plane perpendicular to VP and inclined at 50 to HP, cuts the cylinder and passes through a point on the axis at a height of 50mm above the base. Draw the isometric view of the truncated portion of the cylinder. 17. A hexagonal prism of base side 20mm and height 50 mm rests on the ground plane on one of its rectangular faces with its axis inclined at 30 to the picture plane. A corner of the base is touching the picture plane. The station point is 60mm in front of the picture plane and lies in a central plane that bisects the axis. The station point is 40mm above the ground plane. Draw the perspective view of the prism. (or) 18. A cube of 35mm edge lies with a face on the ground and an edge on the picture plane. All the vertical faces are equally inclined to the picture plane. The station point is 80mm in front of the PP and 60mm from the ground. The edge of the cube in contact with the picture plane is situated 10mm to the right of the station point. Draw the perspective of the cube. 19. The plinth of a computer office measures 15 x 10m. Provide a room for the EDP manager and a room for technical supervisors. Draw the plan and sectional elevation of the office if the ceiling height is 3.3 meters. Assume any other data required. (or) 20. Draw the plan and elevation of a simple storied residential building of plinth area 100m2. Thickness of the wall is 200mm. Adopt a suitable scale.
