Application of UML and Rational Rose in mechanical CAD

The idea and methods of the Object-Oriented technology are presented for the design and realization of a mechanical CAD system, some methods of development for a mechanical CAD system are discussed based on UML by the tool of Rational Rose. It is significative to import UML to the developing of mechanical CAD system and to research the application of UML in mechanical CAD system. This quickens the developing of Object-Oriented CAD system, accelerates the application of Object-Oriented method in engineering software, promotes the expansion and maintenance of software. All of these will provide some new thinking and methods for the development of mechanical CAD system.
