"《工程图形通信入门第四版》是一本专为工程和技术学生设计的教材，由Gary R. Bertoline教授编撰，他本人是普渡大学计算机图形技术系的教授，同时也是Envision数据感知中心的主任。该书旨在介绍工程图形的传统与现代方法，通过可视化、绘图、制图、CAD软件以及三维建模，为学生提供坚实的图形方法基础。在书中，作者不仅涵盖了传统的工程制图技术，如线条、形状和比例等基本原理，还探讨了CAD（计算机辅助设计）的最新进展，以及如何将其整合到工程设计流程中，以提高效率和精确度。这使得学生能够理解和掌握在工程领域中至关重要的图形交流能力，无论是设计概念的表达，还是复杂结构的三维可视化，都得到了深入剖析。 Bertoline教授拥有丰富的教学经验，他曾在圣亨利高中教授初中和高中的图形学，也在韦恩州立大学湖校区和俄亥俄州立大学 Columbus分校教授工程图形技术。他的学术生涯专注于CAD在工程图形和可视化领域的融合，这体现在他所撰写的众多出版物和10部教材中，反映了他对这个领域的深厚理解和实践积累。通过阅读《工程图形通信入门第四版》，读者不仅能学习图形设计的基础知识，还能了解到如何将这些技能应用于现代设计软件，如AutoCAD、SolidWorks或Revit等，以及如何利用这些工具进行创新和解决问题。这本书不仅是工程师的必备参考，也是对图形设计师和技术爱好者的理想教程，帮助他们提升专业素养，推动工程领域的发展。"

Problems

Use the worksheets provided at the end of this section to

complete the problems.

1.1 Research and report on an important historical figure

in engineering design, such as Henry Ford, Thomas

Edison, the Wright brothers, or Alexander Graham Bell.

1.2 Identify at least five other individuals who worked as

engineers and had an impact on society.

1.3 Research and report on an important historical engi-

neering achievement, such as airplanes, space flight,

computers, or television.

1.4 Identify three new products that have appeared on

the market in the last five years.

1.5 Research and report on an important historical figure

in graphics, such as Gaspard Monge, M. C. Escher,

Thomas Edison, Leonardo da Vinci, Albrecht Durer,

or Frank Lloyd Wright.

1.6 To demonstrate the effectiveness of graphics commu-

nications, write a description of the object shown in

Figure 1.15. Test your written description by having

someone attempt to make a sketch from your

description.

12 Introduction to Graphics Communications for Engineers

1.7 Make a sketch of a common device, such as a tele-

phone, automobile, computer mouse, or coffee cup.

1.8 Get a clear mental picture of a television, then sketch

what you see in your mind. Is this mental image 2-D

or 3-D? Try to put words to each feature of the TV

you are drawing. In this problem you will experience

the difficulty in trying to verbally describe an object

with enough detail for it to be manufactured.

1.9 Interview a practicing engineer or technologist and

ask how graphics are used in his or her daily work.

1.10 Ask the practicing engineer or technologist what

changes are taking place in his or her profession.

1.11 Research and report on an important historical fig-

ure in computer graphics, such as Ivan Sutherland,

Steve Coons, R. E. Bezier, or George Lucas.

1.12 Draw the border lines and title blocks for the ANSI

and ISO drawing sheets, using the dimensions

shown. Add text as shown, using a″ (3 mm) all-caps

text (Figure 1.16).

1.13 See Figure 1.17. Using a scale of a′′=1′–0′′, draw

the truss shown in the figure. The rise (R) is one-

fourth the span of the truss.
