4 Drafting & Design
General Features of
the Text
Each chapter begins with a list of objectives
covered in the chapter. A list of technical terms
is also provided to introduce important ter-
minology. Important terms appear in boldface
italic type throughout each chapter. In addition,
certain CAD terms, such as command names
and drawing functions, are identified in fi
boldface
sans serif
type.

Review questions have been added to every
chapter in this edition to test student comprehen-
sion of the material. Each chapter concludes with
a chapter summary, and many chapters feature
an Additional Resources section listing suggested
materials and learning sources for further study.
Many new drafting problems have been added
in this edition to test both manual and CAD
skills.

Step-by-step manual and CAD drafting
procedures are presented in this book in Chap-
ters 6–19. The drafting procedures apply the
concepts related to the material covered in each
chapter. Color backgrounds and graphic icons
set off the drafting procedures from the rest of
the text. The manual drafting procedures are
indicated by a blue background. The CAD draft-
ing procedures are indicated by a purple back-
ground. A tan background is used in cases where
a manual procedure is immediately followed by
an equivalent CAD procedure. In addition, the
manual drafting procedures have a triangle
icon in the heading, and the CAD drafting pro-
cedures have a drawing axes icon in the head-
ing (as shown above). Most of the manual and
CAD drafting procedures appear in succession,
so that each approach is illustrated for a given
problem. For each pairing of procedures, the
manual procedure is presented first to illustrate fi
how traditional drafting principles are applied.
In most cases, a single manual drafting proce-
dure is directly followed by an equivalent CAD
procedure. In some cases, two or more manual
drafting procedures are presented before the
equivalent CAD procedure. This organization
is used when alternate manual drafting proce-
dures are given. In most chapters, the drafting
procedures appear after general or introductory
instruction.
The CAD drafting procedures are intended
for use with a CAD program and can be com-
pleted using the commands and functions of
a typical program. Each CAD procedure is
designed to serve as an equivalent technique for a
given manual drafting procedure. Because there
is typically more than one way to solve a draft-
ing problem with CAD, alternate approaches
are suggested in certain applications. This helps
students identify the most effi way to work ficient
the procedure and select the most appropriate
drawing tools.
Drafting Problems

The text features a wide variety of drafting
problems to provide realistic problem-solving
experiences. Manynewproblemshavebeenadded

problems are designated as introductory, inter-
mediate, or advanced.
Many of the problems from the text are
included in the Worksheets supplement. The
Worksheets supplement is intended for manual
drafting work, but most of the problems that
appear can also be completed as drawings using
a CAD program. The Worksheets problems are
provided in electronic format (as DWG files) on fi
the Instructor’s Resource CD supplement.
