Question

A point is in 4th quadrant 10 units away from the horizontal plane and 20 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 got this question by my school teacher while I was bunking the class.

This question is from Projection of Points in Fourth Quadrant in portion Projection of Points of Engineering Drawing

Answer 1

Right choice is (b) 10, 20

The explanation is: Given object is point placed in 4th quadrant the top view gives the distance from the vertical plane (20) and front view gives the distance from horizontal plane (10) both are placed overlapped in orthographic projection since the object is placed in 4th quadrant.
