Design and Implementation of PCADS on Microcomputer

Many problems exist ia developing a system of designing a. machine part on microcomputer. This paper gives some algorithms to solve these problems, and gives also introduction to a real realized CAD system-PCADS. The combinati on module structure is used in programming system and the methods in developing the system are used to make the system more practical, more general, more integra tive and easier to use. The system was authenticated by The Committe of Science and Technology of Jiangsu Province. It proved to be advanced in our country.
