Title: Create auxiliary views and revolutions.
Course: Engineering Drawing and Design (21106-36) > Section: Producing Illustrations

Creation should include the concept that auxiliary views and revolutions are used to describe the true shape of inclined and oblique planes and should include

- choosing the primary orthographic view from which the auxiliary view is projected
- demonstrating that the edge view of the inclined surface is perpendicular to one of the three principal planes
- establishing a projection plane parallel to the inclined surface
- identifying the true length, depth, or height in the primary (orthographic) view
- illustrating the true size and shape of all features in the auxiliary view.

Process/Skill Questions:

- What is an auxiliary view, and for what is it used?
- What are the steps in drawing auxiliary views?
- Why should one not dimension an inclined plane when it is displayed on an orthographic projection?
- Why would secondary auxiliary views be needed?
