INSTRUCTIONS
(1) Assume appropriate data and state your reasons
(2) Marks are given to the right of every question
(3) Draw neat diagrams wherever necessary

1 (a) A line AB 100 mm long is tangent at the top of a circular disc of 70 mm diameter. The point A is at the top of the circumference. The line AB rolls around the circumference of the circular disc in a clock wise direction. Draw the locus of the end 'A' , till the end B touches the hexagon. Name the curve.

1 (b) Pictorial view of a block is shown in the figure. Draw its
(i) FV along X.
(ii) RHSV
9 M

2 For the given pictorial view, draw:
(i) Sectional FV (section B-B)
(ii) TV
(iii) RHSV
(iv) Insert atleast 10 major dimensions.

3 A pentagonal pyramid, 40 mm edge of the base and axis height 70 mm is resting on one of its corner of base in the VP. The edge opposite to the corner is parallel to and 45 mm in front of VP and parallel to HP. Draw the projections when its apex is nearer to the observer.
15 M

4 (a) A hexagonal prism with edge of base 30 mm and height 70 mm has its edge of base in VP and the base surface inclined at 30° to VP and perpendicular to HP. Draw its projections.
6 M
4 (b) Figure shows FV and TV of an object. Draw its isometric view using natural scale.
9 M

5 A hexagonal pyramid base 25 mm side , axis 55 mm long has its base on HP, with an edge of base parallel to VP. A section plane perpendicular to VP and inclined at 60° to HP bisects the axis of pyramid. Draw FV, sectional TV, true shape of the section and development of lateral surface of pyramid after removing apex.
15 M

6 (a) Line AB 70 mm long is inclined at 30° to HP and 60° to VP. Its end A is 10 mm above HP and 20 mm in front of VP, while its end B is in 3rd quadrant. Draw the projections of line AB.
9 M
6 (b) Draw isometric projection using given FV and LHSV.
