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?
