The course occurs in several parts, beginning with the fundamentals of drawing content, orthographic projection, and freehand sketching; it then moves on to more advanced topics such as auxiliary views, section views, and conventional representations. The final part of the course includes coverage of items such as screw threads, machined features, tolerances and fits, assemblies, bill of materials, and drawing revisions. Rationale: Engineering drawings are the language of industry, used to convey design information from the designer to the manufacturer, inspector, or end user. The ability to understand the engineering information contained on drawings is therefore crucial to all aspects of the engineering technician’s or technologist’s activities. Additionally, the knowledge and skills acquired in this course are applied in subsequent courses in the program.

These are distributed to each student during the first week of class. Course Specific Policies and Expectations: 1. 2. 3. 4. 5. 6. 7. 8. Classes will be comprised of lectures, discussions, and assigned activities, as required. Students are expected to take good notes and to maintain effective organization of their course materials (lecture notes, class handouts, homework, tests, etc.). The use of cell phones or cameras is not permitted in class. Regular attendance of lectures is important for success and students are expected to attend all classes. Students are responsible for catching up on any material missed due to absence. Students are expected to attempt all exercises and assigned work (homework) and, in the case of difficulty, seek further information as needed from available resources (professor, text book, class notes, posted solutions, etc.). Feedback from students has indicated that working through the homework assists greatly in developing student understanding of the course material Industrial drawings will be referred to, where needed, to complement the course text. Physical models, overlays, etc. will be used, where needed, to clarify visual interpretation of 3D shapes. Students will be encouraged to offer solutions to issues covered in class. Tests will be approximately 50 minutes in length and quizzes approximately 10-15 minutes. No consideration will be given to those absent from tests or quizzes unless a valid reason such as sickness is established. Students are advised to see the professor as soon as possible prior to the test, or else immediately after returning to school. Failing this, a grade of zero will be assigned. Durham College Course Outline – DRFT 1107 – 2012 - 2013 Page 6 of 7 Subject Eligibility for Prior Learning Assessment & Recognition (PLAR) Yes No (Candidate eligibility is outlined in the http://www.durhamcollege.ca/assets/Section~specific/Continuing~Education/documents/plar.pdf) PLAR acknowledges subject mastery earned through work experience, professional development or nontraditional educational opportunities. The assessment can be written, oral, portfolio, or observational (or a combination of these four formats). Assessment format is to be determined by the subject matter experts. A candidate will not be able to initiate the PLAR process if s/he: a) registered in the said subject within the last 10 months; or b) audited the subject within the last ten (10) months; or c) previously failed the subject (within the last 2 academic years); or d) Misrepresented his/her performance in a College subject for the purpose of obtaining marks or recognition. Applications for PLAR should be completed prior to subject commencement. In any case, students enrolled in the subject must apply and make payment for PLAR within the first two weeks of subject commencement. General Course Outline Notes: 1.
