Title: Prepare primary auxiliary views.
Course: Drafting: Mechanical (21102-II) > Section: Performing Mechanical Drafting and Design Operations with Extensive Use of CADD

Preparation 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
- creating a projection plane parallel to the inclined surface
- defining the true length, depth, or height in the primary (orthographic) view
- defining the true shape of the auxiliary view
- annotating all views.

Process/Skill Questions:

- What is the purpose of creating auxiliary views of inclined surfaces?
- How is the true length, depth, or height in the primary (orthographic) view defined?
- How is the true shape of the auxiliary view defined?
