Q:14 Which of the following is not true in case of Oblique Projections?
(A) Parallel projection rays are not perpendicular to the viewing plane.
(B) Parallel lines in space appear parallel on the final projected image.
(C) Used exclusively for pictorial purposes rather than formal working drawings.
(D) Projectors are always perpendicular to the plane of projection.


Answer: (D)

Explanation: 

 

(A) → Parallel projection rays are not perpendicular to the viewing plane. TRUE
(B) → Parallel lines in space appear parallel on the final projected image. TRUE
(C) → Used exclusively for pictorial purposes rather than formal working drawings. TRUE

(D) → Projectors are always perpendicular to the plane of projection. False

The projectors in oblique projection intersect the projection plane at an oblique angle to produce the projected image, as opposed to the perpendicular angle used in orthographic projection. 

So, option (D) is correct.
