For Freshman or Introductory courses in Engineering and Computer Science.


Engineering has always required graphics to communicate ideas. However, the transition from hand drawings to computer-aided design has resulted in many important concepts being left out of the standard engineering curriculum. This book is a compact resource that connects traditional engineering graphics with computer-aided design.


Compact coverage of many concepts - Key topics are efficiently explored, providing students with a solid foundation in the fundamentals.


Basic concepts, conventions, and terminology for engineering graphics - Although when using CAD, computers handle the "busywork," engineers still need to master the basic concepts of engineering graphics.


Freehand sketching - Chapter 3 provides an in-depth exploration of this often-overlooked skill, necessary to engineering design.


Computer aided design (CAD) - Students gain an understanding of the underlying concepts of computer-aided design as well as exploring examples of how CAD can be used to generate complex parts and assemblies.


Standard practices for engineering drawings - Even when using CAD, engineers need to understand and implement standard engineering conventions for dimensions, sections, and fasteners.


Tolerancing is covered in detail - To enable students to provide tolerances on their drawings, the text explains basic and advanced concepts in tolerancing, including Geometric Dimensioning and Tolerancing.


Objectives at the beginning of each chapter outline the material to help guide students through the chapter.


Easy to read and understand format, including examples and figures, makes the material accessible to students.

New to this Edition

New sections are included on:

- Sketching auxiliary views

- Modeling a part in CAD
