Introduction to Solidworks SolidWorks is a high-tech company specialized in developing 3D mechanical design software[3].The purpose of the company is to provide powerful CAD/CAE/CAM/PDM systems for design engineers.SolidWorks, the leading product of SolidWorks, is a world leader in 3D CAD software.In 1995, SolidWorks launched the first 3D CAD system developed based on Windows, and became the first computer platform CAD system in the world. Promoted by SolidWorks, other relevant software has been successively launched at home and abroad.SolidWorks is also the first CAD company to develop automatic feature recognition FeatureWorks software and Internet based electronic drawing publishing tool (E-Drawing).In 1997, Dassault acquired SolidWorks with a wholly-owned capital of US $310 million.After the merger, SolidWorks continued to operate independently, becoming a high- quality professional company. SolidWorks Software has pioneered many innovative features, including top-down and bottom-up design.The ability to design relevant design sub components from top to bottom in the assembly environment, so that geometric shapes and components are fully automatic and relevant, and provide consistent interfaces and commands for designers in the fully automatic and relevant design environment.Bottom up design refers to the combination of all parts of a product into a designed product, which can also realize the full automation between geometric shapes and parts. The fully automated design environment provides consistent interfaces and commands. In SolidWorks, users can use various modules and plug-ins, such as part library, feature tools, measurement tools, assembly tools and simulation tools, to design and build various types of 3D models.These tools can help users complete model design efficiently and carry out rapid simulation and analysis. SolidWorks also provides a wealth of community support and training resources, including online tutorials, video training, community forums and professional training courses. These resources can help users better learn and master the use of SolidWorks, so as to improve their work efficiency and design quality. mailto:topacademicjournals@gmail.com Academic Journal of Science, Engineering and Technology Vol.6, Issue 6; November - December 2021; 1252 Columbia Rd NW, Washington DC, United States https://topjournals.org/index.php/AJSET/index; mail: topacademicjournals@gmail.com 14 | A c a d e m i c J o u r n a l o f S c i e n c e , E n g i n e e r i n g a n d T e c h n o l o g y | https://topjournals.org/index.php/AJSET In SolidWorks, configuration is a very convenient function. Users can create variations of multiple parts in a single part and assembly documents, and these parts can be displayed in the same assembly part at the same time.This function is very useful in the specific design process, such as whether the casting blank or the processed state of the part that realizes the sheet metal bending.In addition, SolidWorks uses configuration to capture changes and modifications in the actual design process, thus meeting a variety of design requirements.SolidWorks also created a real-time online 3D website (Partstream. Net) for Internet based 3D product catalog management and delivery services, as well as advanced functions such as SmartParts, flexible subassemblies, and alternate position views.This is because SolidWorks has powerful configuration management technology, and other similar software cannot support such advanced features. In short, SolidWorks is a powerful three-dimensional CAD software, which has led the development of many innovative functions in the CAD industry. Driven by SolidWorks, the application of 3D CAD software has been widely popularized. 3.2. Appearance design 3.2.1.
