The process of corrugated carton chart's parametric design to solve some data processing problems in parametric design by using AutoCAD second development platform was introduced, including numerical value of forms and procedure in the process. In numerical value, firstly various query forms were transformed into Microsoft Access relational database. Procedure is that certain logical data are stored in program way. Corresponding data in the form, which was established on the basis of VBA and combined with the known products information gained from customers inputting, were retrieved out. Finally the system calculates automatically the optimized size of the carton structure parameters and then draws the cartons spreading drawing.
