Question

A rectangular plate of sides 60 x 30 cm has its shorter side in the V.P, inclined to 60 degrees with V.P and 30 degrees with the H.P. The top view while drawing projections in 1, 2 and 3 are ______  ________ and ________ respectively.

(a) line, line, parallelogram

(b) line, parallelogram, line

(c) rectangle, square, square

(d) rectangle, square, parallelogram

The question was asked in an online interview.

My query is from Projection of Oblique Plane in portion Projection of Planes of Engineering Drawing

Answer 1

Correct answer is (a) line, line, parallelogram

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