Question

A point is in 4th quadrant 15 cm away from the vertical plane and 10 cm 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 posed to me in exam.

I want to ask this question from Projection of Points in Fourth Quadrant topic in section Projection of Points of Engineering Drawing

Answer 1

The correct choice is (b) 10, 15

The best I can explain: 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 4th quadrant.
