Fundamentals of Technical Graphics concentrates on the main concepts
and principles of technical graphics and provides users with the informa-
tion they need most in an easy and straight forward manner. The book is
divided into two volumes: Volume I contains Chapters 1 to 5, w here as
Volume II comprises of Chapters 6 to 10. The chapters and topics are orga-
nized in a sequence that makes learning a gradual transition from one level
to another. However, each chapter is presented in a self-c ontained manner
and may be studied separately. In each chapter, techniques are presented
for implementing the topics treated. Chapter 1 gives the basic informa-
tion a beginner needs to get started with drafting. Chapter 2 focuses on
basic sketching tools and techniques. Chapter 3 discusses computer design
drafting (CDD) systems and provides relevant information to make the
student an informed user of the systems. Chapter 4 covers shape con-
struction, the foundation of creating drawing views. Chapter 5 presents
the principles and techniques for creating standard multiview drawings.
Chapter 6 discusses auxiliary view creation, whereas Chapter 7 focuses
on section view creation. Basic dimensioning is covered in Chapter 8.
Isometric pictorials are presented in Chapter 9. Working drawings are
covered in Chapter 10, the heart of drafting, and practical information
is provided for creating them. The Appendixes provide introductory dis-
cussions about screw fasteners, general and geometric tolerancing, and
surface quality and symbols.
