Question

The perspectives of all horizontal lines inclined at 45 degrees to the picture plane converge to a distance points on the _______________

(a) ground line

(b) perpendicular axis

(c) horizon line

(d) center of vision

The question was posed to me in unit test.

My question is taken from Types of Perspective topic in chapter Oblique & Perspective Projection of Engineering Drawing

Answer 1

Correct option is (c) horizon line

Best explanation: The distance points are equidistant from the center of vision the distance of each from the centre of vision being equal to the distance of the station point from the picture plane the perspectives of all horizontal lines inclined at 45 degrees to the picture plane converge to a distance points on the horizon line.
