CADD-100 Principles of Drafting
The objective of this course is to introduce students to the language of graphics used in engineering and technology. Students will acquire an understanding of orthographic projections, sections, conventions, threads and fasteners, pictorial drawings, auxiliaries, and revolutions. Mechanical assembly and detail drawings, architectural plans and elevations, and elements of electrical/electronic and printed circuit drawings are discussed and illustrated. Other topics covered are lettering, scaling, dimensions, holes, fillets, rounds fasteners, fittings, and title block specifications. Students use drawing instruments, such as the triangle, ruler, and compass and do some free-hand sketching.
