Course Number and Title: EDD 131 Engineering Graphics/CAD
This course covers the development of basic drafting skills using traditional drafting equipment with special emphasis on computer-aided equipment. The focus includes two-dimensional drawings and the development of orthographic projections with a variety of design problems and study activities to help the student conceptualize and communicate graphically.
- Interpret mechanical drawing and blueprints. (CCC 1, 2, 5, 6; PGC 1, 3)
- Draw basic architectural plan views. (CCC 1, 2, 5, 6; PGC 1, 3)
- Hand sketch designs using graph paper. (CCC 1, 2, 5, 6; PGC 1, 3)
- Draw designs and layouts using common orthographic and pictorial methods with computer-aided drafting software. (CCC 2, 5, 6; PGC 1, 3)
- Detail computer-aided design/drafting (CAD) generated working drawings using proper dimensioning and annotation techniques. (CCC 2, 5, 6; PGC 1, 3, 4)
- Produce solid models and machine assemblies using 3D solid modeling software. (CCC 1, 2, 3, 5, 6; PGC 1, 3, 4, 6)
- Create a product prototype using additive manufacturing. (CCC 1, 2, 3, 5, 6; PGC 1, 3, 4, 6)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
