Question

A cube is resting on H.P on one of its corners with a solid diagonal perpendicular to the V.P. What are the top views of 1st, 2nd, 3rd stages while drawing orthographic projections?

(a) Rectangle, rectangle, regular hexagon

(b) Square, irregular hexagon, irregular hexagon

(c) Rectangle, rectangle, irregular hexagon

(d) Square, regular hexagon, regular hexagon

I have been asked this question in an online interview.

Query is from Projection of Solids with Axes Inclined to both Horizontal and Vertical Plane in chapter Projection of Solids of Engineering Drawing

Answer 1

Right option is (b) Square, irregular hexagon, irregular hexagon

Easiest explanation: As in the 1^st stage the cube is to be placed in the position occurred when the diagonal of base perpendicular to V.P so top view gives square and then rotated so as to keep one of the corners only on H.P so the top view will be irregular hexagon then if we make diagonal perpendicular to V.P the top view will be irregular hexagon.
