Question

A line is in vertical plane and perpendicular to horizontal plane at a distance of 10 cm from horizontal plane and 5 cm from profile plane. What is the distance from vertical reference line to line?

(a) 10 cm

(b) 0 cm

(c) 5 cm

(d) 7.5 cm

I had been asked this question in examination.

My doubt stems from Projection of Line Perpendicular to one of the Plane topic in division Projection of Lines of Engineering Drawing

Answer 1

Correct option is (c) 5 cm

To explain: Given the line is in vertical plane and perpendicular to a horizontal plane at a distance of 10 cm from horizontal plane and 5 cm from profile plane. So the distance from vertical reference line to line is 5 cm.
