534 Chapter 16 Engineering Drawings and Symbols
Summary
Now that you have reached this point in the text
- You should have a good understanding of the importance of engineering drawings in con-
veying information to other engineers, machinists, and assembly personnel. - You should understand what is meant by orthographic views, isometric drawing, and solid
modeling. - You should understand the basic rules required for an engineering drawing, including show-
ing dimensions, specifying material size, and indicating finished surfaces. - You should know when to use isometric views and sectional views.
- You should be familiar with the different types of sectional views.
- You should understand the importance of solid modeling in conveying concepts and exam-
ining parts for their ability to fit with other parts. - You should know why we need and use engineering symbols to communicate among
ourselves. - You should be familiar with some of the common civil, electrical, and mechanical engineer-
ing symbols so that you can understand and interpret a technical drawing.
participating in multicultural activities on campus
and by attending seminars and public lectures in areas
outside their own disciplines. Students can also pre-
pare themselves for practicing engineering in a global
context by availing themselves of any opportunities
for interacting with students and professors from uni-
versities in other parts of the world. An increasing
number of universities have student exchange pro-
grams which can be very beneficial in broadening the
outlook of participants. One of the experiences that
had a big positive impact on my own training as an
engineer was the long vacation that I spent in Zurich,
Switzerland, working with other students in a factory
which manufactured turbomachinery. This experience
was made possible by the International Association
for the Exchange of Students for Technical Experi-
ence (IAESTE).
After spending all these years teaching engineer-
ing in Ghana I decided to seek new challengeselsewhere prior to my retirement. I am currently
working as a visiting professor in North Carolina
Agricultural and Technical State University in the
United States of America. Teaching engineering in
America is quite a different experience because of the
differences in the teaching and learning resources and
the different backgrounds of the students. However,
my experiences confirm to me the fact that no matter
where they study, all engineering students require the
same thing to prepare them for successful professional
life: development of critical thinking and good prob-
lem-solving skills. As a student you should realize that
when your professors always insist that you present
your assignments in a clear and orderly manner, or
when they insist on meeting deadlines for turning in
assignments, they are helping you to acquire the skills
necessary for you to succeed not only in the practice
of engineering but also in the non-professional aspects
of your life.62080_16_ch16_p504-549.qxd 5/22/10 12:31 AM Page 534
