Title: Prepare secondary 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 not perpendicular to any of the three principal planes
- creating the point view of a true-length line
- creating an edge view of the auxiliary surface, using the point view
- defining true length, depth, or height in the primary (orthographic) view
- defining true shape of the auxiliary view
- annotating all views.

Process/Skill Questions:

- What is another name for a surface not perpendicular to any of the principal planes?
- What practical application may require the construction of a secondary auxiliary view?
