Question

A line of length 15 cm is parallel to horizontal plane and 10 cm away from it and making an angle of 45 degrees with profile plane. The distance from line to xy reference line in front view will be __________

(a) 15 cm

(b) 10 cm

(c) 7.07 cm

(d) 10.06 cm

This question was posed to me in an internship interview.

I'd like to ask this question from Projection of Line Inclined to one Plane and Parallel to other in chapter Projection of Lines of Engineering Drawing

Answer 1

The correct answer is (b) 10 cm

Easy explanation: Given line is of any length but we are asked distance from line to xy reference line in front view which is the distance from the line to horizontal plane even if the line may inclined to other planes.
