Objective AutoCAD is used to draw the carton box structure, in order to improve the work efficiency， we need to develop a box / carton CAD system based on AutoLISP. The main task of software development work was to complete the work flow of the system, the overall development plan and program design. Methods In the development process, the following methods were used: node description by relative polar coordinate, parametric design, the combination of box/carton-type library with box/carton components library, and assembly design, and the AutoLISP language was used for program design. Results In this program, the parametric drawing for box/carton structure could be achieved according to the mathematical model which was built with CAD. And in the same time, the system had functions of input data legality verification, error handling, output expansion plan, and automatic dimensioning. Conclusion In practical application, this system could largely reduce repeated work in the design, and facilitate the follow-up work.
