Question

An ellipse is placed parallel to vertical plane which of the following projection is false?

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

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

(c) Ellipse is perpendicular to horizontal plane

(d) The traces of plane containing this circle will not intersect at xy reference line

The question was posed to me in an interview for job.

I'd like to ask this question from Projection of Planes Parallel to one of the Reference Plane topic in section Projection of Planes of Engineering Drawing

Answer 1

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

For explanation I would say: Given an ellipse parallel to vertical plane so the plane containing ellipse 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 hexagon. As the object is ellipse which has major and minor axis the views show different lengths.
