       Course Name: Engineering Graphics

       Credits: 3 (2 lecture; 4 lab)

II.    Prerequisite


III.   Course (Catalog) Description

Course covers scope of engineering graphics. Content includes lettering; geometric construction; sketching; multiview; projections; auxiliary views and sections; shop processes; dimensioning; tolerancing; anonometric and oblique projections; fasteners; assembly drawings; descriptive geometry; graphs and computer-aided design. Three-dimensional Computer Aided Design CAD) integrated throughout the course.

IV.   Learning Objectives

Graphics can be defined as an instrument of creativity, evaluation, and communication.  Sketching and CAD techniques should be integrated in this course to achieve the following outcomes:

  • Introduce design as a structured process and demonstrate this process through project work
  • Analyze the engineering function of existing products
  • Apply design principles and rationale in a realistic and original design project.
  • Work in a team to generate, analyze, evaluate and select among engineering design solutions to meet specified requirements
  • Create functional description of the design intent
  • Develop design objectives
  • Build functional physical model and test it
  • Ability to functionally analyze an engineering system and it’s component parts
  • Apply drawing standards to your work
  • Propagate 3D parametric CAD data to manufacturing and business units
  • Demonstrate communication skills, engineering ethical awareness, and teamwork skills necessary to succeed in engineering environment
  • Demonstrate proficiency in freehand sketching to communicate design ideas
  • Convert between pictorial and multiviews.
  • Demonstrate spatial visualization and reasoning skills by using  3D parametric solid modeling analysis
  • Interpret and create working drawings:
  • Convert between pictorial views and multiview drawings.
  • Create appropriate section views from given multiview drawings
  • Create a properly dimensioned and toleranced multiview drawings using engineering standards
  • Create appropriate auxiliary views from given multiview drawings
  • Create complete working drawings with detailed part drawings and assembly drawings

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VII.  Methods of Instruction

Instructions will include lectures, films, and working on special projects (group and individual).  Students will also receive individualized guidance in solving workbook and CAD problems during the class period.

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

  1. Attendance - Mandatory
  2. Satisfactory completion of all assigned workbook drawings and the CAD project.
  3. Passing three examinations (a make-up test will only be given if medical reasons precluded taking the examination on the date scheduled).

Course may be taught as face-to-face, media-based, hybrid or online course.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
