Computer-aided design and drafting (CADD) is the process of using a computer
with CADD software to design and produce drawings and models according to
specific industry and company standards. The terms fi computer-aided design (CAD) and
computer-aided drafting (CAD) refer to specifi aspects of the CADD process. This chapter fic
introduces the AutoCAD CADD system. You will begin working with AutoCAD and
learn to control the AutoCAD environment.
AutoCAD Applications AutoCAD Applic a tion s
AutoCAD commands and options allow you to draw objects of any size and
shape. Use AutoCAD to prepare two-dimensional (2D) drawings, three-dimensional
(3D) models, and animations. AutoCAD is a universal CADD software program that
applies to any drafting, design, or engineering discipline. For example, use AutoCAD
to design and document mechanical parts and assemblies, architectural buildings,
civil and structural engineering projects, and electronics.
2D Drawings
2D drawings display object length and width, width and height, or height and
length in a fl at (2D) form. 2D drawings are the established design and drafting format fl
and are common in all engineering and architectural industries and related disci-
plines. A complete 2D drawing typically includes dimensions, notes, and symbols
that describe view features and information. This practice results in a document used

command: An
instruction issued
to the computer to
complete a specific
task. For example,
use the LINE
command to draw
line objects.
option: A choice
associated with a
command or an
alternative function
of a command.
