Does the SolidWorks mechanical design engineer paint parts individually or draw parts in an assembly?
Either way, in actual work, the two approaches may alternate.If you do is mechanism design, may be other assembly references, can consider each part separately draw, so in the future by other assembly references when good maintenance, no loss of reference.If you do need to consider other parts of the related parts, such as the appearance of the skin, a variety of sports organizations, etc., can be considered to create parts in the assembly, can avoid some mistakes when combined with other parts. However, it is still recommended that you minimize the external reference in the assembly and make the key features that require external reference, and that the rest of the features are still done in an independent part manner.
There are two ways, corresponding to "bottom up" and "top down" two design methods.
In the overall design of the product, can put each parts of a product are designed, then get the assembly components, after assembly to check whether all parts of the design meets the requirements, whether interference exists, if you need to modify, change are separate parts, and then in the assembly test again until the end, fully meet the design requirements. Since the whole process is down (component), it is impossible to plan the product from the very beginning, and how many parts of the product can be determined only after all the parts have been completed. This method will be modified because there is no prior to the careful planning and effective. This bottom-up design can be used in the case of ready-made products, and in the case of a single product range. But in the new product design or product series rich and changeful circumstances, it seems very inconvenient.TOP-DOWN design refers to the analysis of the finished product, and then down design. The main frame of products as the main component, and the product is decomposed into components, sub assemblies, and then identifies the main component element and its related characteristics, finally understand the relationship between components and internal components, and to evaluate the product assembly. With this information, you can plan and design and grasp the overall design intent in the model.It can manage large components, but also can effectively grasp the design intent, make a clear organizational structure, not only can quickly transfer the design information, in the same design group to achieve the purpose of sharing information, can also transfer the same design information in the design team between different, to the purpose of cooperative combat. Thus, in the early stages of design, through rigorous communication management, can make different design departments synchronous product design and development.
