Question

A circle is placed parallel to vertical plane which of the following projection is false?

(a) Front view-circle, top view- line

(b) Length in top view and side view will be same

(c) Circle is perpendicular to horizontal plane

(d) The traces of plane containing this circle intersect at xy reference line

I got this question by my college director while I was bunking the class.

Origin of the question is Projection of Planes Parallel to one of the Reference Plane in portion Projection of Planes of Engineering Drawing

Answer 1

The correct choice is (d) The traces of plane containing this circle intersect at xy reference line

Easiest explanation: Given a circle parallel to vertical plane so the plane containing circle is perpendicular to horizontal plane and profile plane. The top view and side view gives a line and front view gives the true shape and size of circle. The traces will intersect at line formed by intersection of profile plane and horizontal plane.
