GET 102 ORTHOGRAPHIC DRAWING Objective Question
Take CBT

Question

The document uses an analogy of suspending an object inside a 'hinged box' to explain orthographic projection. What is the primary purpose of this analogy?
Options
A To illustrate the material properties of the object
B To show how to unfold the projection planes to obtain different views
Correct Answer
C To demonstrate the effect of light on the object
D To explain the historical context of engineering drawing
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 5 explains the hinged box analogy: 'The orthographic projection can be thought of as suspending an object inside a hinged box and projecting the points to the planes which make up the box before unfolding the box.' This directly relates to how the different views are obtained and laid out.

Hint

Consider what happens to the 'box' after the projections are made onto its 'walls'.
