Computer aided system for sheet metal pattern development application : an object-oriented approach

This study presents an object-oriented approach to the design and implementation of a computer-aided system for sheet metal pattern development application. The construction of a pattern is the most vital step in any sheet metal work. The pattern must be correct both in shape and dimensions. Its accuracy is also highly desirable. A computer program can help ensure that these qualities are achieved. The program decomposition was based on abstract units called objects. The primary object of concern is the three-dimensional geometric object representing the metal project. The design was implemented on a language that supports the Object-Oriented Programming paradigm. The design and implementation of the program exhibits inheritance, reusability and extensibility
