Course Number and Title: EDD 233 Engineering Drafting and Design III
In this advanced drafting course, students reinforce their knowledge of engineering drawing and its applications. This course includes the theories of all types of section, detail and assembly, welding, and development drawings. Surface texture, geometric dimensioning and tolerancing (GD&T), and threaded and miscellaneous fasteners are also discussed in depth.
- Describe and draw full, half, offset, revolved, removed, aligned, and broken-out sections. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 3, 4, 5)
- Prepare a complete set of working drawings. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 3, 4, 5)
- Describe and prepare welding drawings. (CCC 1, 2, 3, 4, 5, 6, 7; PGC 1, 3, 4, 5)
- Describe and draw radial line and parallel line development drawings. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 3, 4, 5)
- Interpret and apply GD&T to drawings. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 3, 4, 5,)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

- Prepare drawings with conventional revolutions and conventional breaks.
- Prepare a complete set of working drawings.
- Draw a complete set of working drawings, including details, assemblies, and parts lists.
- Prepare written specifications of purchase parts for the parts list.
- Properly group information on the assembly drawing with identification numbering systems.
- Explain the engineering change process, and prepare engineering changes.
- Describe and prepare welding drawings.
- Identify welding processes.
- Draw welding representations, and provide proper welding symbols and notes.
- Draw weldments from engineering sketches and actual industrial layouts.
- Describe and draw radial line and parallel line development drawings.
- Draw surface development drawings.
- Draw radial line and parallel line development drawings.
- Explain when stampings are used.
- Interpret and apply GD&T to drawings.
- Explain the purpose of geometric tolerancing.
- Use datum feature symbols and datum target symbols on drawings.
- Properly place geometric characteristic, material condition, and material boundary symbols in feature control frames.
- Describe methods for identifying datum surfaces, target points, areas, lines, center planes, and axes on drawings.
