Question

The 2nd quadrant is in which position?

(a) Below H.P, behind V.P

(b) Above H.P, behind V.P

(c) Above H.P, in-front of V.P

(d) Below H.P, in-front of V.P

This question was addressed to me in unit test.

I need to ask this question from Planes of Projections and Four Quadrants topic in section Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

Right choice is (b) Above H.P, behind V.P

The best explanation: The position of reference planes will be similar to quadrants in x, y plane co-ordinate system. As the 2nd quadrant lies above the x-axis and behind the y-axis here also the 2nd quadrant is above H.P, behind V.P.
