Research and Apply on Product-level Parametric Modeling

Aiming at the shortages that product-level main variables is too many and parametric parts library can not be reused.This paper puts forward part code to encapsulate the part main variable with a description of part as an instance.The product model is built from down to top based on parametric parts library. Moreover,product code is adopted to encapsulate product-level main variable and chain data structure is applied to transfer variable value,drive and establish parametric product model.Using the above method,parametric mould frame model is founded.An application example is given to demonstrate that this method is efficient and stable.
