Introduction

• Many 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 Projection

• No 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 Method

• The 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.
