Railway Culvert CAD Software System

Abstract

With the development and the widespread application of computer technology, some of the country's railway professional designing institute and software companies have introduced many culvert design application software. There are many culvert CAD system have been applied in engineering practice, but from the view of practical application and software development, there also have many shortcomings, such as the operation is inconvenient, the function is not perfect, the mapping function does not conform to the designing habits, the function of inheritance and generality is not strong, the management functions of design information and design results is lack and so on.This paper aims at the standardization; normalization characteristics of culvert designing, the parameterization culvert design method were studied, analyzed the data organization structure, the culvert length calculation method, the parametric design and drawing method, then based on them, use the object-oriented programming method, at the VC++6.0 programming platform, developed the railway culvert CAD software systems which based the ObjectARX technology.The software system which has been developed realized the engineering quantity calculation, engineering drawing and engineering quantity form output, improving the efficiency of culvert designing and mapping.
