Question

What is additional 3rd view on orthographic projection in general for simple objects?

(a) Front view

(b) Top view

(c) Side view

(d) View at 45 degrees perpendicular to horizontal plane

This question was addressed to me at a job interview.

This intriguing question comes from Basics of Orthographic Projections in chapter Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

Correct answer is (c) Side view

The best explanation: In general for simple objects engineers use only front view and top view or else front view and side view or else top view and side view. If every view is visualized side view gives height and thickness of object.
