3.1 Analysis of the Application of UG software in the Modeling of Parts
Use the UG design software, its advantage is very obvious, can be combined with the characteristics of different parts, parts selection of different design methods, this design is not only convenient, but also easy to learn, in the different toolbar also contains different commands, designers can according to the actual requirements, select the most suitable design method, can quickly complete the design of different parts. On this basis, UG software using the method of parametric design, the design has some relevance between different toolbar commands to modify the design, components, with convenient and reliable advantages. The change in parts design module, you can choose to automatically. As can be rapid response to the assembly drawings, correlation module and fast response. In the assembly model and engineering drawings of parts, modifications can be a direct reaction to the change in part for, do not need to use two-dimensional CAD diagram to modify the parts, do not have to make changes in the assembly drawing, so prone to low error, change or leakage problems. Using the UG software designers can take the work focus to structure design, is convenient for modification and design, designers can design parts of the structure.[2]
