Design and Implementation of computer Aided Decorative Design System

This paper fully considers the system in the technology of inheritance and innovation, to fully grasp the principles and concepts of the decorative arts, as well as the basic process of computer aided design based on, the system of research and analysis of demand. Then, according to the system requirements analysis and feasibility study, and the overall design of the system, including the system function division and module design, on this basis, the use of Mel scripting language system. At last, the system is tested and further improved. This topic comes from the actual demand, combined with the actual application requirements, the paper mainly introduces the design and implementation process of the computer aided design system based on the prototype method and MEL language. The system is based on the knowledge of software engineering as the guiding ideology of the design and development of the system, the main function of the system includes user management system, modeling module works, the material setting module, lighting layout module, script sharing and management module and so on. In addition, the paper uses the UML modeling technology to analyze the system, to ensure the system design of the normative. Papers in the system architecture design, module realization and system integration, basically follow the rational function, the humanized principle, extension principle and the principle of modular design. This ensures that the system maintenance and reliability; the of decorative art of material, scale, form and environment characteristics and computer aided system were combined effectively, ensure the availability of system functions and good user experience.
