Purpose:
Engineering drawing is basic to all engineering and technical fields. This course will teach you how to
lay out a mechanical design according to accepted standards so it can be built. Descriptive geometry
will be introduced during the last half of the course. From this you will solve spatial relation problems
using graphical methods. Visualization is stressed throughout. Computer aided drafting (CAD) will be
used as a "tool" for the above and mixed in with manual methods. A design project at the end ties the
course together and will be done as a team, emphasizing the design process.
Materials:
Pencil and pen
Three-ring notebook – required - containing this syllabus, all your homework and notes.
Engineering computation paper
Equipment:
 4" draftsman compass with F lead
 3" divider
 Mechanical lead holder or pencils with HB and 4H (or comparable) lead
 Pencil pointer (if using mechanical lead holder)
 Ames Lettering Guide
 Erasers - Staedtler Mars - Plastic is good
 Scales: engineer's & architect's
 30-60-90 Triangle, 8"
 45-45-90 Triangle, 8"
 Dusting brush, masking tape, cleaning rags
NOTE: A "package" for the above is available at the bookstore.
1 GB “flash” drive – optional
Grading:
Grading is based primarily on drawings (plates). Each drawing is worth 20 points. Points are based on
neatness and accuracy. There will be a few quizzes, at random times, and a final. These will be worth
up to one-fourth of your grade. There are no makeup’s as the general rule. Students are expected to be
at each class. If you are sick, call my office (or email) and leave a message before class. This class is
very fast paced. Daily attendance is mandatory! Grade is also based on attendance. Working together
and comparing homework is encouraged; giving someone your computer work is cheating.

Quizzes are given at random – they may or may not be announced. You are expected to read
assignments and to know something. I may give reading quizzes over assigned reading prior to
the material being discussed. These will be true or false, knowing concepts and definition of
terms. My expectation is that you should be able to get 10 out of 15 points on quizzes of this
type. These reading quizzes will be given in the first ten minutes of class – if you are late, you
miss the quiz.
In addition to reading quizzes, there will be “in class draws” which require that you know the
techniques of drawing that we will have studied.
Homework: You can plan on one to two hours of work outside of class for every hour in class. Homework
is viewed as practice for the method and principle that was explained during class. Work must
stand alone, be neat, be labeled as explained in class. Homework is graded on neatness, format,
effort, completeness, and accuracy. You are encouraged/required to compare your work with
your classmates.
No late homework is accepted unless you have previously called (emailed) telling me that you
are sick or some other valid reason. Homework points count the same as quiz points. If you
don’t do the homework you will not pass this class.
Attendance: If you are not attending class, you will not pass. You must be in class, on time, every day.
There are no make-ups for quizzes or homework unless you are sick (or some other valid
excuse) and have called my office (or email) before class. Often I will have you do 10 point,
in-class exercises. If you are not present, you generally cannot make these up even with a valid
excuse.
Additional:
Turn off all cell phones before entering class.
Use lab time for me to help you on ENGR 103 – do not be working on other classes.
All material turned in for grading (exams, quizzes, homework) must be done in pencil - not
pen. Homework is to be labeled neatly, with answers circled or underlined Any work that is
not done neatly will be returned without being graded.
If you have a handicap that requires some special consideration, please let me know so that you
can be accommodated.
Please, no eating or drinking during class. With computers and drafting tables, drinking
coffee, pop, or even water, can lead to a disastrous mess.
If you terminate your participation without officially withdrawing your final grade will be 0.0.
WELCOME!
Please read and sign below that you have read and understand the class standards
and expectations.
Outcomes:
You must know and be able to apply the rules of drafting to make drawings that can be built.
These drawings will be both manual and CAD.
You must be able to graphically visualize and utilize descriptive geometry to solve engineering
problems.
You must function as a team member, understand the design process, and be able to produce a
quality product both individually and as a team.
Teamwork/Design Project: Engineering accreditation wants to see teamwork and a knowledge of the design
process. You will be organized into 3 or 4 person teams. Get to know your teammates and use
them. Engineering is a tough curriculum to go it alone. Work and compare on homework.
You will have a term project – this is a team grade. You must organize and cooperate to
succeed.
Final Exam: The final exam will be comprehensive (with a manual drafting portion and a CAD portion) and
be individual. This is a instrument to assess your knowledge of the subject matter – it is not a
learning tool. You will not get it back and we will not go over it. Your work must be neat,
complete, and make sense. It is scheduled for Thursday, 18 June.
Cheating:
The definition of cheating is any unfair advantage over your classmates. Having copies of
homework or quizzes from past years is an unfair advantage. Comparing homework answers
and methods is encouraged. Copying another’s homework is cheating. Using another
person’s computer work and putting your name on it is cheating.
Your Attitude: You are responsible for your learning of the material. Engineering is a rewarding but
demanding curriculum/profession. For some, you will find that the curriculum is too
demanding. Please heed the above warnings – if this is not your quarter for this course, depart
now and, perhaps, later will be better.
My Attitude: I hope that I can help you succeed. I will do my best. Unfortunately, sometimes engineering
means “grinding away” on problems that do not come easily. This is part of the learning
process. I am not doing any favors passing anyone who later falls on their face. Read the
material, attend class and pay attention, do the homework and compare with your teammates.
Do this, and you should accomplish the course Outcomes, pass the class, and feel secure in
your future success as an engineering student. Again, welcome!
I have read the above and understand the course expectations.

ENGR 103/quarter and year
Welcome to Engineering 103
Things to know about the course and my expectations
Engineering is a very rewarding but demanding profession. I am convinced that a person with
average intelligence who has some mathematical, creative and visualization ability can be a successful
engineer. What it does take is perseverance, focus, and commitment.
Engineering is the application of science, math, experience, etc. to do something useful for
society. Understanding the theory is not enough. Society (and more specifically your company) will
pay you to get good answers and results – close does not count in the real world. Hence, focus and
attention to detail is very important. You will find that I am a stickler on details, deadlines, and
format. Do not take shortcuts. Read the text, be at all classes on time, be attentive, ask questions,
and start on the homework immediately while it is fresh in your mind. Check with your
classmates/teammates on answers and procedures. Engineering is a team profession – going it alone
can be disastrous.
Often I will explain how to do something differently than the text author or change the
requirements of the problem. Please keep in mind that I see the text as supplementing my instruction –
not the other way around. You are not being trained as a technician – you are being educated as an
engineer. The difference is that you will not simply be duplicating problems that I have shown.
Instead, you must be able to think critically and apply the theories to new problems. Unfortunately,
this means that sometimes you must “grind away” at a problem. This, too, is part of the learning
process. As I have said, engineering takes perseverance and focus as much as intellectual ability.
Commitment means being willing and able to spend the necessary time to learn the material.
The rule of thumb in college is about two hours outside of class for every hour in class. This means
another 30 hours for a 15 credit class load. This is an average – some weeks it may be more, some
weeks less. You will find that the material moves very fast – much faster than what you may have
been accustomed to in high school. Many of you may really need to re-evaluate your situation in
terms of engineering school, family, and work.
Engineering 103 is not particularly difficult – but it is very time consuming. You can get a
very good grade by simply doing all of the work. Some students have said that this class should be
worth 10 credits. Since you will be credited with only 5 credits when you transfer, making ENGR 103
ten credits is not going to happen. You are being educated as an engineer, not trained as a draftsman.
Consequently, the emphasis in this class is on visualization and thinking. When you are done, I think
that you will find that you got your money’s worth and that you will be well prepared in the graphics
sciences for wherever you transfer.
I will do my part to help you along. All I ask is that you are focused, committed, and are
willing and able to persevere. Again, welcome!
