The document discusses Computer Aided Design and Drafting (CADD). CADD uses computers to help design and draft products, making the process more productive and accurate than traditional manual drafting. It allows for faster modifications, easy duplication of designs, and better storage of drawings. CADD has been widely adopted by 98% of global engineering companies. It introduces standards for design and drafting that improve quality. Using CADD also creates job opportunities in outsourcing.
