1Chapter 9 Auxiliary Views and Editing with GRIPS
- Learning Objectives
- Use 2D Projection method to draw Auxiliary Views.
- Create Rectangles.
- Use the basic GRIPS Editing commands.
- Create and Edit the Plot Style Table.
- Set up and use the Polar Tracking option.
- Create multiple Viewports in Paper Space.
2Introduction
- 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.

3Orthographic 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.
4Folding 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.

7Using 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.
