Abstract: PDM/Creo digital design platform has greatly promoted the efficiency of R ＆ D and design and ensured the consistency of data models.High quality and complete 3 D model is the key to ensure the effectiveness of platform data source.In the design process of 3 D model, the manual input of material parameters will seriously affect the design efficiency, and data errors may occur.Therefore, it is necessary to create the material library.By uniformly calling the material files in the material library, not only is the design efficiency improved, but also the unification of the same material parameters is ensured, thus improving the standardization level.
