Question

A point is 50 cm away from the vertical plane and horizontal plane 80 cm away from profile plane in 3rd quadrant then the projections is drawn on paper the distance between the front view and top view of point is _____________

(a) 130

(b) 100

(c) 160

(d) 0

I got this question in homework.

This key question is from Projection of Points in Third Quadrant topic in portion Projection of Points of Engineering Drawing

Answer 1

Right answer is (b) 100

To explain I would say: Since the point is 50 cm away from the horizontal plane the distance from the point to xy reference line will be 50 cm. And then the point is at distance of 50 cm from the vertical plane the distance from reference line and point will be 50 cm, sum is 100 cm.
