It is defined by a set of parameters to express the characteristics of the shape of the product, these parameters control the design and results, adjustment parameters can be modified so as to achieve the purpose of the model. Accountants can directly start the organization in motion analysis module in ProEngineer, defined according to the design intent of the connection mechanism, the servo motor and run the analysis mechanism, the relative movement of the parts and the whole trajectory between the observation means to detect the interference of the machine. And the use of the module, designers also can be a variety of measurements and saves the results of the analysis in the form of videos.Application of parametric design can easy to implement serialization designed to shorten product development cycles,reduce duplication of design, saving development costs.
