Question

A square is placed in between the reference planes in such a way that one diagonal is inclined to H.P and another diagonal inclined to V.T. Projections are drawn. The top views in 1, 2 and 3 stages are _______  _________ and __________ respectively.

(a) line, line, parallelogram

(b) line, parallelogram, line

(c) square, line, parallelogram

(d) square, rhombus, rhombus

I got this question during an interview.

I'm obligated to ask this question of Projection of Oblique Plane topic in chapter Projection of Planes of Engineering Drawing

Answer 1

The correct answer is (d) square, rhombus, rhombus

The explanation: As initially the plane is assumed to be parallel to H.P the top view will be square and then the plane is tilted with respect to H.P to required angle the top view will be square compressed to rhombus. Finally the plane is tilted with respect to V.P then rhombus will just turn w.r.t V.P.
