Dr. Patrick J. Hanratty, who created the CHERRY INSTITUTE in 1957, is considered the founder of CAD software. The Cherry Institute created the first commercial CAD program, PRONTO. Dr. Hanratty, an engineer, realized how computers could automate design. He developed software to make design faster, more accurate, and more efficient with computers. , released in 1965, was developed at the Cherry Institute. revolutionized engineering and design. It let engineers use computers to develop and alter designs. This made design faster and more accurate.success spawned additional CAD software, which is now vital for engineers and designers in many industries. Today's CAD software is based on Dr. Hanratty's work at the Cherry Institute. His notion of employing computers to assist the design process changed engineering and design, and his influence continues on in today's CAD applications.
