Question

A point is 2 units away from the vertical plane and 3 units away from profile plane and 7 units away from horizontal plane in 1st quadrant then the projections are drawn on paper the distance between the front view and side view of point is ______________

(a) 10

(b) 5

(c) 9

(d) 7

The question was asked in examination.

I want to ask this question from Projection of Points in First Quadrant in section Projection of Points of Engineering Drawing

Answer 1

Right choice is (b) 5

Explanation: Since the point is 3 units away from the profile plane the distance from the point to reference line will be 3 units. And then the point is at a distance of 2 units from the profile plane the distance from reference line and point will be 2 units, sum is 5.
