The work aims to design the program based on ArtiosCAD function statement, so as to achieve the interactive design of carton components of folding carton. According to the examples of insertion folding carton, the design of specific steps combined with the variables in ArtiosCAD and the method used to add the components to the ArtiosCAD box parts library were further discussed. Compared with the way of drawing with geometrical tools, the efficiency was improved by over 50%. The proposed method can greatly improve the efficiency, convenience and flexibility of the package structural design.
