Question

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

(a) 10 cm

(b) 5 cm

(c) 6 cm

(d) 0 cm

The question was asked in a job interview.

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

Answer 1

The correct option is (d) 0 cm

Easy explanation: Top view gives the distance from object to xy reference line and object to reference line between the profile plane and horizontal plane. But here the line is placed vertical to horizontal plane so the view will be point and also the line is in vertical plane to distance will be zero.
