CGD4 Technical Computer Graphics II
4-units 2hrs lec a wk, 6hrs lab a wk by arrangement.

Course Description: Intermediate industrial computer graphics including advanced dimensioning, tolerancing, surface manipulation, geometric intersections, and modeling for solids and rendering. An open exit/entry supervised class which allows for shortened semester schedule with a corresponding increase in lab time. The student is allowed an individual cooperative environment on selected projects. Students may concurrently enroll in CGD110 and CGD9. Note: The emphasis of this class is experimenting with visual geometry (math) by manipulating objects and the space around them.

Course Prerequisites: Satisfactory score on the English placement exam or a grade of "C" or better in English 250; completion of Mathematics 233 or two years of High School Algebra with grades of "C" or higher or satisfactory Math placement. Discuss this with your instructor-emphasis on mental visualization using surfaces, points, and lines in space to create objects.

Required Texts: Other Graphic texts as required by the subject areas Engineering Graphics Communication.

Required Course Materials: 3.5" Diskettes-3 to 5 (1.44) & Zip 100 mb disks, 8.5" X 11" Sketch Pad.

Units: Intermediate computer graphics manipulations, Tolerancing Geometric intersections, surfaces, shapes (using rendering for geometry integrity). Dimensioning surface and shape manipulation using various techniques, modeling for solids and intermediate wire armature construction.

Expected Student Outcomes: At the conclusion of this course the student will,

• Create a drawing of singular objects using the computer.
• Create a drawing of an object comprised of several parts.
• Be able to apply advanced dimensioning techniques to various mechanical objects. (This includes calculating distances, angles, and tolerances).
• Use geometry of points, planes, intersections. (Plain and solid geometry)
• Theory with applications to various technology areas.
• Use solid modeling/manipulation of various objects symmetrical/ asymmetrical.
• Use rendering of surfaces and solids for object/geometry verification.
• Apply "isometric drawing" as drawn on the drawing board.
• Apply and use orthographic projection-sections-details-auxiliary views.
• Apply and use standard drafting sheet layouts.

Class work and schedule of content: Student work is turned into the instructor upon completion for instructor evaluation. Lectures and class demonstrations are linked to the class progress and need. All student work is assembled into a student portfolio.

Grading: Ability to apply drawing commands 80%. Tests 10%, classroom self management 10%. Extra work and/or special projects are accepted as part of a student's grade.

Tests: Tests are administered at the conclusion of each study area. Tests are performance involving drawing on the computer and written using the word processor.

Attendance: Students are expected to attend the assigned class times and arranged lab times. Failing to attend will result in incomplete projects and drawing practice times.

Class requirements for completion: Completion of assigned projects. Assembled portfolio of all class work. Participating in the drawing and written tests.

Students requiring special services or arrangements because of hearing, visual, or other disability should contact their instructor, counselor or the Disabled Student Services Office. Occupational/Vocational students-Limited English language skills will not be a barrier to admittance to and participation in Vocational Education Programs.

Students are expected to exercise academic honesty and integrity. Violations such as cheating and plagiarism will result in disciplinary action which may include recommendation for dismissal.
