Course Description:
All products, and parts for products, are engineered, designed and manufactured from mechanical drawings. These drawings call out the specifications, material composition, dimensions and tolerances of the specific part. Certain conventions must be followed and understood to create these drawings and to interpret them. This course enables the student to understand the conventions of orthographic projection so that their, lecture may replicate or repair the component to original specifications. Certain types of drawings, such as assembly drawings, show disassembly and reassembly procedures which are necessary for repair and maintenance of most machines.

Instruction is provided by textbook with associated workbook, lecture and group discussion.
