Abstract: For the expression demand of the whole product modeling rules,a frame model concept was put forward,and the logic,graphics and scripts expressions of its instantiation operation were given.With the scripts way,a semantic model for describing the product modeling rules was proposed based on frame model,thus a modeling method of whole product parametric was established.The whole product modeling process could be described top-down by descriptive semantics of modeling rules,the modeling details could be ignored when describing the whole product modeling laws,and the final model could be finished by configuration during design stage.Compared with other methods,the expression efficiency of whole product modeling rules was improved significantly.The whole product parametric system could be rapidly developed to meet the specific needs through expanding parts and modeling regulations.

Key words: modeling rule, frame model, descriptive semantics, top-down, whole product parametric
