Catalog Description: ET 482 – Application of computer aided design techniques utilizing industrial
software within a workstation environment.
Textbook: Parametric Modeling with Autodesk Inventor
Objectives: Upon completion of the course, students will be able to:
 Identify the various sections and commands of Autodesk Inventor software.
 Understand the concepts, benefits, challenges and functionality associated with parametric solid
modeling design.
 Correctly apply modeling and editing commands with constraints and model information to
produce intelligent solid model designs.
 Create working drawings, exploded assemblies and bills of material based on parametric models.
 Use shading, lighting and animation commands in order to successfully produce basic illustration
and animation designs.
 Identify other parametric solid modeling design systems; distinguish differences and similarities
between the competing software.
 Develop skills, which will enable the learning of other solid modeling systems.
Evaluation:
 Attendance & Participation (400 points: 12.1%): 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 (1600 points: 48.5%): Approximately 10-12 projects will be assigned during the
semester. Each week’s work is worth 120 - 135 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 next class period.
 Quizzes (300 points: 9.1%): Two quizzes will be given during the semester. Each quiz will
consist of 15-25 questions worth 5-10 points each (150 points per quiz).
 Mid-Term & Final Exam (300 points & 400 points: 9.1% & 12.1%: 21.2% total): The midterm and final exam will consist 30-50 questions worth 5-20 points each.


Semester Personal Project (300 points: 9.1%): The semester personal project will be an object
of the student’s choice. Degree of difficulty and quality of design will determine points earned.
Bonus (extra credit) points available for extra effort/results of project.
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 (based on 3200 pts):
93% - 100% = A (2960 - 3200 points)
90% - 93% = A- (2868 - 2959 points)
87% - 90% = B+ (2772 - 2867 points)
83% - 87% = B (2640 - 2771 points)
80% - 83% = B- (2548 - 2639 points)
77% - 80% = C+ (2452 - 2547 points)
73% - 77% = C (2320 - 2451 points)
70% - 73% = C- (2228 - 2319 points)
67% - 70% = D+ (2132 - 2227 points)
63% - 67% = D (2000 - 2131 points)
60% - 63% = D- (1908 - 1999 points)
Less than 60% = F (1907 or less points)
89% - 80% = B (2624 – 2953 points)
79% - 70% = C (2294 – 2623 points)
69% - 60% = D (1963 – 2293 points)
Less than 60% = F (1962 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 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 encouraged to discuss this matter with the instructor.
Late Assignment Policy:
 Any assignment that is turned in one class late will be penalized by the loss of ten (10) percent
plus any assignment 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.
Test Schedule: Test schedule is tentatively set as below. The schedule is subject to change and all tests
will be announced in advance.
