Course Number and Title: EDD 141 Engineering Drafting and Design I
In this course, students are introduced to engineering drafting. Topics include a study of geometric construction, proper use of drafting equipment, freehand sketching, lettering, orthographic projection, forming and machining processes, dimensioning methods, and sectioning and pictorial drawings. The standards and practices recommended by American National Standards Institute (ANSI) and American Society of Mechanical Engineers (ASME) are followed.
- Define and interpret graphic language and the proper tools and equipment used to construct mechanical drawings. (CCC 1, 2, 5; PGC CAD 1, 3, 4 ; DEM 1, 2, 3, 4, 6)
- Assemble technical sketches to communicate ideas and planning. (CCC 1, 2, 5, 6; PGC CAD 1, 3, 4, 5; DEM 1, 3, 4, 6)
- Properly letter the uppercase single stroke gothic style alphabet and numerals. (CCC 1, 2, 5, 6; PGC CAD 1, 3, 4, 5; DEM 1, 6)
- Define and construct basic geometric shapes using manual instruments. (CCC 1, 2, 5, 6; PGC CAD 1, 2, 3, 5; DEM 1, 2, 3, 4, 6)
- Draw the shape and size of objects through the use of orthographic and pictorial views in accordance with ANSI. (CCC 1, 2, 5, 6; PGC CAD 1, 2, 3, 4, 5; DEM 1, 2, 3, 4, 6)
- Describe and apply basic dimensioning techniques on multi-view and pictorial drawings. (CCC 1, 2, 5, 6; PGC CAD 1, 3, 5; DEM 1, 2, 3, 4, 6)
- Describe the most commonly used shop terms and methods of fabrication. (CCC 1, 2, 5; PGC CAD 3, 4, 5; DEM 1, 5, 6)
