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 front 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

The question was posed to me in homework.

This interesting question is from Projection of Oblique Plane in portion Projection of Planes of Engineering Drawing

Answer 1

Correct answer is (a) line, line, parallelogram

The best explanation: As initially the plane is assumed to be parallel to H.P the front view will be line and then the plane is tilted with respect to H.P to required angle the front view (line makes angle with H.P) remains line. Finally the plane is tilted with respect to V.P then parallelogram will form in front view.
