Answer all five questions

All questions carry equal marks

1. a) A point P is 20mm above HP and 30mm in front of VP. Another point Q is 30mm below HP and 40mm behind VP. Draw projections of both the points on the same reference line.

   b) A line AB is 75mm long. A is 50mm in front of VP and 15mm above HP. B is 15mm in front of VP and is above HP. Top view of AB is 50mm long. Draw its projections and find inclination with HP.

   A regular pentagon of 30mm side has one side on the ground. Its plane is inclined at 45° to the HP and perpendicular to the VP. Draw its projections.

2. A cone, base diameter 50mm and axis 65mm long, has its base on the HP. A section plane perpendicular to the VP and inclined at 30° to the HP cuts the cone, bisecting the axis. Draw the front view, sectional top view and true shape of the section.

   A hexagonal prism, side of base 25mm and height 50mm rests with one of its sides on HP such that the axis is inclined at 30° to the HP and parallel to VP. Draw its projections.

3. Draw isometric view of a hexagonal pyramid, with side of base 30 mm and height 65 mm. The axis is vertical and two edges of the base are parallel to the VP.

   OR

   Draw isometric projection of a sphere resting centrally on top of a cube of sides 50mm.

5. A cylinder of base diameter 50 mm and height 70 mm rests on its base on HP. A section plane perpendicular to VP and inclined at 45° to HP cuts the cylinder such that it passes through a point on the axis 20 mm from the top end. Draw the development of the surface of the remaining portion of the cylinder.

   OR

   A pentagonal prism, side of base 30 mm and height 60 mm, stands vertically with its base on HP and an edge of the base parallel to VP. A section plane inclined at 60° to HP cuts the prism passing through the midpoint of the axis. Develop the lateral surface of the truncated prism.
