I got this question by my school teacher while I was bunking the class.

My enquiry is from Projection of Planes Parallel to one of the Reference Plane topic in section Projection of Planes of Engineering Drawing

Answer 1

The correct choice is (d) line, line, line

The best explanation: If a plane is parallel to vertical plane then the top view and side view gives a line and front view gives the true shape. If a plane is parallel to horizontal plane then the front view and side view gives a line and top view gives the true shape. If a plane is parallel to profile plane then the top view and front view gives a line and side view gives the true shape.
