1(a)(i) Draw the projections of the following points on the same XY line, keeping convenient distance between the projectors . Also state the quadrants in which they lie-
a. 30mm below HP and 25mm behind VP
b. 35mm below HP and 30mm in front of VP
c. On HP and 30mm in front of VP
d. On HP and 35mm behind of VP

1(a)(ii) The end A of a line AB is in HP and 25mm in front of VP . The end B is in VP and 50mm above HP . The distance between the end projectors when measured parallel to the line of intersection of HP and BP is 65 mm. Draw the projections of the line AB and determine its true length and true inclinations with HP and VP.

1(b) A circular lamina inclined to the VP appears in the front view as an ellipse of major axis 30mm and minor axis 15mm . The major axis is parallel to both HP and VP . One end of the minor axis is in both the HP and VP . Draw the projections of the lamina and determine the inclination of the lamina with the VP

2 A square pyramid 35 mm side of base and 60 mm axis length rests on HP on one of its slant edges. Draw the projections of the pyramid when the axis is inclined to VP at 45°
40 M

3(a) A cube of sides 40mm is resting on HP with its base on HP such that one of its vertical faces is inclined at 30° to the VP. It I cut by a section plane perpendicular to VP, inclined to HP at an angle 45° and passes through the midpoint of the axis. Draw the development of the lower lateral surface of the cube.

3(b) A cone of base diameter 40mm and height SOmm rests centrally over a frustum of pentagonal pyramid of base side 45mm and top side 35mm and height SSmm. Draw the isometric projection of the combined solid .
