Question

A line AB is placed in such a way that the distance from A and B to vertical plane are 5 and 10 cm and distances from A and B to horizontal plane are 4 and 8 cm each. The traces would present ______________

(a) one on above and other below reference line

(b) below the reference line

(c) on xy reference line

(d) above the reference line

This question was posed to me during an online interview.

My question comes from Traces of a Line topic in division Projection of Lines of Engineering Drawing

Answer 1

The correct answer is (c) on xy reference line

The explanation is: As the corresponding distances from vertical plane and horizontal plane are in same ratio we can say the line may act as symmetry for both the vertical and horizontal plane so the traces would fall on xy reference line.
