Question

A point is in 2^nd quadrant 15 units away from the vertical plane and 10 units away from the horizontal plane. Orthographic projection is drawn. What is the distance from point of front view to reference line, top view point to reference line?

(a) 15, 10

(b) 10, 15

(c) 0, 15

(d) 10, 0

This question was addressed to me in an international level competition.

Origin of the question is Projection of Points in Second Quadrant topic in portion Projection of Points of Engineering Drawing

Answer 1

The correct option is (b) 10, 15

For explanation: Given object is point the top view gives the distance from vertical plane (15) and front view gives the distance from horizontal plane (10) both are placed overlapped in orthographic projection since the planes need to rotate to draw projection as the object is placed in the 2nd quadrant.
