Question

A line of 12 cm length is perpendicular to profile plane and the least distance from this line to profile plane is 6 cm. This is at a distance of 4 cm from vertical plane and 5 cm from the horizontal plane. What is the distance from the line to xy reference line in front view?

(a) 0 cm

(b) 6 cm

(c) 4 cm

(d) 5 cm

I have been asked this question in unit test.

Origin of the question is Projection of Line Perpendicular to one of the Plane topic in section Projection of Lines of Engineering Drawing

Answer 1

Correct answer is (d) 5 cm

For explanation: Given a line of 12 cm length is perpendicular to a profile plane and the least distance from this line to profile plane is 6 cm. This is at a distance of 4 cm from vertical plane and 5 cm from the horizontal plane. So the distance from the line to xy reference line in front view is 5 cm.
