Question

A point is in 2^nd quadrant 20 units away from the horizontal plane and 10 units away from the vertical plane. Orthographic projection is drawn. What is the distance from point of front view to reference line, top view point to reference line?

(a) 20, 10

(b) 10, 20

(c) 0, 20

(d) 10, 0

I had been asked this question in an online quiz.

This key question is from Projection of Points in Second Quadrant topic in chapter Projection of Points of Engineering Drawing

Answer 1

Correct option is (a) 20, 10

To explain: Given object is point placed in 2^nd quadrant the top view gives the distance from vertical plane (10) and front view gives the distance from horizontal plane (20) both are placed overlapped in orthographic projection since the object is placed in the 2nd quadrant.
