wireframe model:
The most basic 3D
model—contains
only information
about object edges
and the points
where edges
intersect, known as
vertices; describes
the appearance of
the model as if it
were constructed
from wires.
surface model:
A 3D model that
contains information
about object edges,
vertices, and the
outer boundaries of
the object, known
as surfaces; surface
models have zero
thickness, lack
mass, and may not
enclose a volume.
solid model: The
most complex 3D
model—contains
information about
object edges,
vertices, surfaces,
and mass; solid
models enclose a
volume.
walkthrough: A
computer simulation
that replicates
walking through or
around a 3D model.
flythrough: A
computer simulation
that replicates flying
through or around a
3D model.

AutoCAD provides commands and options to accurately create 2D drawings for building
design and construction, such as this architectural floor plan of a home.

to manufacture or construct a product. 2D drawings are the conventional and often
required method of communicating a project. Figure 1-1 shows an example of a 2D
architectural floor plan created using AutoCAD. Use this textbook to learn how to
construct, design, dimension, and annotate 2D AutoCAD drawings.

3D models allow for advanced visualization, simulation, and analysis typically
not possible with 2D drawings. AutoCAD provides commands and options for developing
wireframe, surface, and solid models. An accurate solid model is an exact
digital representation of a product. Add color, lighting, and texture to display a realistic
view of the model. See Figure 1-2A. Use view tools to view the model from any
angle. See Figure 1-2B. Apply animation to a model to show product design or function.
For example, you can perform a walkthrough of a model home or a flythrough
of a model civil engineering project. AutoCAD and Its Applications—Advanced
provides detailed instruction on 3D modeling and rendering.

Designing and drafting effectively with a computer requires a skilled CADD operator.
To be a profi cient AutoCAD user, you must have detailed knowledge of AutoCAD
commands and processes and know which command and process is best suited for
a specifi c task. You must also understand and be able to apply design and drafting
systems and conventions when using AutoCAD.
As you begin your CADD training, develop effective methods for managing
your work. First, plan your drawing sessions thoroughly to organize your thoughts.
Second, learn and use industry, classroom, or offi ce standards. Third, save your
work often. If you follow these procedures, you will fi nd it easier to use AutoCAD
commands and methods, and your drawing experience will be more productive
and enjoyable.
drawing sessions:
Time spent working
on a drawing
project, including
analyzing design
parameters and
using AutoCAD.
