Abstract: The article introduced the construction scheme of two dimensional rapid layout design system for railway vehicle and its practical applications. The configurable system was designed through analyzing the structure characteristics of the railway vehicle functional unit and the interface relationship, based on the concept of parametric design and the vehicle two dimensional plane-section layout design process, using redeveloped program based on AutoCAD/Windchill. The system implemented the configuration, addition and modification of background parameterized device block, centralized management and permission assignment of background data. Rapid shape selection of the vehicle template, rapid deployment and modify of device block, parametric drive of device block were achieved by user-friendly navigation interface. Then the rapid design of plane-section drawings was implemented. It was standardized the configuration and operation methods of two dimensional rapid layout, ensured the design process bottom-to-top and the accuracy of design data flow, shortened the product development cycle, improved the quality of a qualified research and development.
