Q.2 (a) Construct an isometric scale of length 80mm. 4
(b) Draw the isometric projection to isometric scale of an inverted cone (diameter=70mm, height=75mm) with the circular face on top and its axis perpendicular to the H.P. Give all the dimensions. 7
(c) A hexagonal pyramid of base edge 25mm and height 50mm, is placed centrally on the top face of a square prism of base side 80mm and height 20mm. Two of the opposite edges of the hexagonal base of the pyramid are perpendicular to the V.P. The common axes are perpendicular to the H.P. Draw the isometric projection of the combination to isometric scale and Give all the dimensions and indicate the direction of viewing. 13
