IntroductionMany designs have features located on inclined surfaces that are not parallel to the regular planes of projection. To truly describe the feature, the true shape of the feature must be shown using an auxiliary view. An auxiliary view has a line of sight that is perpendicular to the inclined surface, as viewed looking directly at the inclined surface. An auxiliary view is a supplementary view that can be constructed from any of the regular views.

Orthographic ProjectionNo matter what the position of a surface may be, the fundamentals of projecting a normal view of the surface remain the same: The projection plane is placed parallel to the surface to be projected. The line of sight is set to be perpendicular to the projection plane and therefore perpendicular to the surface to be projected. This type of view is known as normal view. In the figure below, the design has an inclined face that is inclined to the horizontal and profile planes and perpendicular to the frontal plane.

Folding Line MethodThe folding-line method uses the concept of placing the object inside a glass-box, the distances of the object to the different projection planes are used as measurements to construct the
necessary views, including the auxiliary views.

Using the AutoCAD Classic Workspace Workspaces are sets of menus, toolbars, palettes, and ribbon
control panels that are grouped and organized so that a user can work in a custom, task-oriented drawing environment. Three task-based workspaces are pre-defined in AutoCAD
2D Drafting & Annotation: drawing environment set for 2D drafting tasks.
3D Basics: drawing environment set for Basic 3D modeling tasks.3D Modeling: drawing environment set for Advanced 3D modeling
tasks.AutoCAD Classic: the classic drawing environment set for 2D tasks.
This environment provides the most drawing area on the screen.
