Emphasis is placed on the proper preparation of technical drawings for microfilming.
Starting with the study of freehand technical sketching technique, the student continues with the study of the fundamental theory of orthographic projection, and of the concepts of dimensioning. An introduction is made to limit dimensioning, to true position and geometric tolerancing, and to pictorial drawing. Topics include threads and fasteners, and an introduction to detail and assembly drawings. Drawings will include use of technical standards, complete detail and assembly drawings, and technical sketches of actual machine assemblies. Included topics are intersections and developments, and use of welding, piping, and fluid power symbols.
