Compared with the similar software, designers can spend less time in designing better products using SolidWorks. Taking design of red wine bottle as an example, software SolidWorks was mainly used for modeling and assembly design. The following functions could be realized: calculating and locating data, generating two-dimensional drawings, completing drawings and modifying the complex models of two-dimension quickly and accurately, rendering the effect of the product and displaying its visual image. Above all, it could reach the results of the maximum stress strain, maximum displacement in the environment and bearing capacity through finite element analysis. In the end, it can help the designers to choose the most reasonable design of the package containers.
