Objectives: Upon completion of the course, students will be able to:
 Identify the various sections and commands of AutoCAD and Inventor software.
 Understand the concepts, challenges and constraints behind design decisions.
 Correctly apply drawing, editing, lettering and dimensioning commands in order to successfully produce
3D industrial drawings and designs.
 Identify other computer-aided design systems, distinguish differences and similarities between the
competing software.
 Develop skills, which will enable the learning of other drafting and/or design systems.
Evaluation:
 Attendance & Participation (400 points: 12.5%): Each student is expected to complete several
reading or research assignments prior to the class period. Class discussions, quizzes, exams,
presentations or written reports could be used to evaluate the fulfillment of this task.
 Assignments (1700 points: 53.1%): Approximately 8-10 projects will be assigned during the semester.
Each week’s work is worth 100 - 150 points. Projects that span multiple class periods are worth the sum
of the weeks’ points. Due dates will be set for each given assignment, but are usually the beginning of
the second week after class period.
 Quizzes (400 points: 12.5%): Four quizzes will be given during the semester. Each quiz will consist of
10-20 questions worth 5-10 points each (100 points per quiz).
 Mid-Term Exam (300 points: 9.4%): The mid-term exam will consist 15-30 questions worth
5-20 points each. There will be a drawing portion worth 50% of the test score.
 Final Exam (400 points: 12.5%): The final exam will consist of 30-50 questions worth 5-20 points
each. There will be a drawing portion worth 50% of the test score.
 Extra Credit: Several extra credit assignments will be presented during the semester. Students are
NOT required to fulfill these activities, but each assignment completed correctly could help raise a final
grade. A grade of ‘80’ or higher is required to receive the extra assignment credit.
Grading Information: All assignments, tests and projects will be graded according to the following scale:
92.5% - 100% = A (2960 - 3200 points)
89.6% - 92.4% = A- (2868 - 2959 points)
86.6% - 89.5% = B+ (2772 - 2867 points)
82.5% - 86.5% = B (2640 - 2771 points)
79.6% - 82.4% = B- (2548 - 2639 points)
76.6% - 79.5% = C+ (2452 - 2547 points)
72.5% - 76.5% = C (2320 - 2451 points)
69.6% - 72.4% = C- (2228 - 2319 points)
66.6% - 69.5% = D+ (2132 - 2227 points)
62.5% - 66.5% = D (2000 - 2131 points)
59.6% - 62.4% = D- (1908 - 1999 points)
Less than 59.6% = F (1907 or less points)
Course Policies: It is expected that students will behave properly in class. Students who disrupt class, or
deface equipment or property will be removed from the classroom and penalized in the current
assignment/project, and in extreme cases with a failing final grade. Cheating will result in FAILING the
course automatically.
Attendance: Do NOT miss classes, attendance and participation are required. Lectures and demonstrations
will occur at varying times during the class period. However, attendance for the entire session is not always
necessary if the required assignments/project has been completed and turned in. Attendance will be recorded
and may affect your final grade. Any absences MUST be accompanied by documented proof of necessity for
full credit. Notification prior to absence will result in partial credit. Each undocumented/no notification absence
will result in a 2% penalty applied to the final course grade.
Students Rights and Responsibilities: It is essential that all students know what is required of them in order to
complete a course satisfactorily. To that end, the Office of the Provost and Academic Vice President
recommends that students become familiar with the guideline concerning their rights and responsibilities. The
guidelines are available online at: www.wiu.edu/provost/student.
Students with Disabilities: In accordance with University policy and the Americans with Disabilities Act
(ADA), students who require special accommodations due to a disability, or any other medical reason, are
encourages to discuss this matter with the instructor.
Special Course Cost: Each student is required to reimburse the department for the cost of the materials
furnished for the class and for lab assignments. The amount that has been established is $25.00 and needs to be
paid in full no later than February 20, 2016 directly to the Engineering Technology department.
Late Drawing Policy:
 Any assignment that is turned in one class late will be penalized by the loss of ten (10) percent plus any
drawing errors or mistakes.
 Assignments that are submitted two classes late will lose twenty (20) percent in addition to the discounts
for errors or mistakes.
 Students who are absent because of a verifiable illness can usually make up missed work, not including
tests. It is the students’ responsibility to check in with the campus medical center, then make
arrangements for make-up work as soon as they come back to class.

announced in advance.
