Question

A point is 7 units away from the vertical plane and 3 units away from profile plane and 3 units away from horizontal plane in 3rd quadrant then the projections are drawn on paper the distance between the front view and top view of point is _______________

(a) 10 units

(b) 8 units

(c) 9 units

(d) 5 units

The question was asked by my college director while I was bunking the class.

I would like to ask this question from Projection of Points in Third Quadrant in portion Projection of Points of Engineering Drawing

Answer 1

Correct choice is (a) 10 units

Explanation: Since the point is 3 units away from the horizontal plane the distance from the point to xy reference line will be 3 units. And then the point is at distance of 7 units from the vertical plane the distance from reference line and point will be 7, sum is 10.
