Aimed at the limitation of existing model in domestic road CAD systems, by analyzing some typical road CAD systems at home and abroad, and combined with the authors' experiences during researching and developing CAD system, the problem about model expression of design object is presented. It is pointed out that with the increasing extension in scale in the construction of highways and airports, in order to strengthen the adaptability of CAD system and to raise the developing level of software, it's found necessary to establish a core model of system. This paper, based on computing geometry and data structure theory, studies the core model of systems in detail and suggests its fundamental content, general structure and fundamental function. At the same time, the research is closely combined with the development of airport CAD software so that it is more practical.
