Engineering Graphics with AutoCAD 2020

Description

James D. Bethune taught drafting and Computer Aided-Design (CAD) for 39 years, twice winning the Outstanding Professor of the year award. He has a doctor’s degree in education from Boston University and has written more than 28 books on drafting and CAD. While retired from full-time teaching, Jim continues to write textbooks on CAD. An avid golfer, Jim lives in East Greenwich, Rhode Island.

• Quickly learn the foundational skills for technical drawing using AutoCAD with step-by-step guidance and nearly 150 exercises to help develop student’s creativity and problem-solving capabilities.
• Step-by-step format throughout the text allows students to work directly from the text to the screen and provides an excellent reference during and after the course.
• Covers the latest in dynamic blocks, user interface improvements, and productivity enhancements.
• Exercise, sample problems and projects appear in each chapter, providing examples of software capabilities and giving students an opportunity to apply their own knowledge to realistic design situations. Includes examples of how to create an animated assembly, apply dimension to a drawing, calculate shear and bending values, and more!
• ANSI standards are discussed when appropriate, introducing students to the appropriate techniques and national standards.
• Illustrations and sample problems provided in every chapter, supporting the step-by-step approach by illustrating how to use AutoCAD and its features to solve various design problems.
