What do you understand by normal and compressed letters?
Draw the projections of a point a, 25 mm in front of the V.P. and 20 mm above the HP.
Explain the aligned system of dimensioning with a simple sketch.
Illustrate solids of revolution with simple sketches.
Why the solids are sectioned?
How is the isometric view of an object obtained?
Distinguish between single curved surface and double curved surface.

Section B Marks 5 each
2. Construct a diagonal scale to read meters decimeters and centimeters for a R.F. of 1/50 and long enough to measure up to 5 meters. Show on it a length of 2.86 meters and 3.48 meters.
3. A straight line AB 70 mm long makes an angle of 45o to the H.O. and 30o to the V.P. The end A is 15 mm in front of V.P. and 20 mm above H.P. Draw the plan and elevation of the line AB.
4. Draw the plan and elevation of a right regular pentagonal prism side of base 25 mm and axis 58 mm long when it is resting on its base on H.P. with one of its rectangular faces making an angle of 30 o to V.P.
5. A pentagonal pyramid edge of base 25 mm and height of axis 60 mm, has its base on the ground and an edge of the base parallel to V.P. It is cut by a plane, the H.T. of which makes an angle of 45 o to the V.P. and is passing 15 mm from the plan axis. Draw the sectional elevation and true shape of the section.
6. Develop the surface of a hexagonal pyramid side of base 28 mm and height 60 mm. The pyramid is resting on its base on the ground and one edge of the base is inclined at 20 o to V.P.

Section C Marks 10 each
7. A cylinder of 50 mm diameter and height 65 mm standing on its base on ground is completely penetrated by a horizontal cylinder of 40 mm diameter and 75 mm long. Their axes intersect each other and are parallel to V.P. Draw the curves of intersection in elevation.
8. A cube of 40 mm sides rests centrally on a square block of 60 mm edges and 20 mm thick. Draw the isometric projections of the two objects with the edges of the two blocks mutually parallel to each other.
9. Using free hand sketching draw the projections of square prism assuming suitable dimensions both in First angle projection method and third angle projection method.
