Question

An upright cone (diameter = 50 mm and height = 70 mm) is placed centrally on the top rectangular face of a pentagonal prism (base side = 50 mm and axis = 80 mm). The pentagonal prism is resting on one of its face edges on H.P. with axis parallel to V.P. and H.P. both. Draw the isometric projection of this combination of solids. Give the dimensions and indicate the direction of viewing.

Answer 1

ISOMETRIC PROJECTION OF COMBINATION OF SOLIDS: 

(i) Helping figure 

(ii) Drawing isometric pentagons of prism 

(iii) Drawing horizontal lines indicating the faces of prism 

(iv) Drawing ellipse of base of cone 

(v) Drawing generators of cone

(vi) Axis, direction of viewing 

(vii) Dimensioning
