CAD stands for Computer-Aided Design. It uses computers and their graphic devices to assist designers in their work. Abbreviated as CAD. In engineering and product design, computers can assist designers with tasks such as calculation, information storage, and drawing. In design, computers are typically used to perform numerous calculations, analyses, and comparisons of different options in order to determine the best one ； Various design information, whether digital, textual, or graphical, can be stored in a computer’s memory or external storage, and can be retrieved quickly ； Designers usually start with sketches, and the tedious task of turning these sketches into working drawings can be done by computers ； The design results automatically generated by the computer can be quickly displayed in graphical form, allowing designers to make judgments and make adjustments to the design in a timely manner ； Computers can be used to process graphic data related to tasks such as editing, zooming in and out, translating, and rotating graphics. CAD can reduce the repetitive tasks such as calculation and drawing for designers, allowing them to focus on the design itself, thereby shortening the design cycle and improving the quality of the designs. 　　Development overview: The first computer-aided drawing system was developed in the United States in the 1950s, marking the emergence of passive computer-aided design techniques with basic drawing output capabilities. In the early 1960s, CAD’s surface patch technology emerged, and commercial computer-aided drawing devices were introduced in the mid-1960s. In the 1970s, complete CAD systems began to take shape. Later on, raster scan displays that could produce realistic graphics appeared, along with various graphic input devices such as manual cursors and graphic input boards, all of which contributed to the development of CAD technology. In the 1980s, with the emergence of microprocessors and memory devices made from powerful very large-scale integrated circuits, engineering workstations were created, and CAD technology gradually became widespread in small and medium-sized enterprises. Since the mid-1980s, CAD technology has evolved toward standardization, integration, and intelligence. Various standard graphic interface software and graphic functions were introduced one after another, playing a significant role in promoting CAD technology, facilitating software porting, and enabling data sharing ； The system architecture has evolved from having a single function in the past to possessing integrated functions, giving rise to computer-aided manufacturing systems that combine computer-aided design with computer-aided manufacturing ； The application of curing technology, network technology, multiprocessors, and parallel processing technology in CAD has greatly improved the performance of CAD systems ； The introduction of artificial intelligence and expert system technologies into CAD gave rise to intelligent CAD technology, which significantly enhanced the problem-solving capabilities of CAD systems and made the design process more automated. Today, CAD is widely used in various fields such as electronics and electrical engineering, scientific research, mechanical design, software development, robotics, the apparel industry, publishing, factory automation, civil engineering, geology, and computer art. The name of SolidWorks, a globally renowned CAD software company, is quite meaningful: “Solid” implies solidity, stability, reliability, and firmness, while “Works” refers to factories and work; literally, it means a company that works diligently and develops in a stable manner. This name is a true reflection of SolidWorks’ relentless efforts over more than a decade to provide high-quality 3D CAD software for the manufacturing industry, thereby achieving its own rapid and healthy growth. On June 30, 2005, SolidWorks held the second China User Conference in Shanghai, with over 800 users, partners, and media reporters attending this event. Mr. John McEleney, the company’s CEO, visited the site for the second time to deliver a keynote speech, once again demonstrating SolidWorks’ strong commitment to China’s manufacturing industry. Solid’s positioning: SolidWorks has a clear and defined vision for its own development. It has been committed to providing the manufacturing industry with cost-effective and user-friendly mainstream 3D CAD software, thereby achieving sustainable growth. History always moves forward, and the development of design tools is no exception; every advancement stems from the culmination of human wisdom across various historical periods. Looking at the history of CAD, the shift from drawing on paper to 2D drawing represented a major leap, while the transition from 2D CAD to 3D CAD was an even greater leap. Before SolidWorks was developed, 3D CAD had been around and in use for many years, but at that time it relied mainly on graphic workstations and UNIX operating systems; due to factors such as high costs and complex interfaces and operations, it was difficult for it to become widely adopted by ordinary users. In the mid-1990s, the first 3D CAD software based on the Windows kernel was created: SolidWorks. The SolidWorks software utilizes the advanced 3D modeling core system Parasolid, taking full advantage of Windows’ powerful capabilities. As soon as this type of 3D CAD software, based on a microcomputer platform and utilizing the WINDOWS kernel technology, was introduced, it eliminated all the shortcomings that had plagued previous 3D CAD systems based on graphic workstations and UNIX operating systems – such as high costs and complex operation – and thus won the recognition and approval of designers. Therefore, SolidWorks’ contribution to the development of 3D CAD is worth being recorded in history. Mr. John McEleney emphasized that, \"The SolidWorks culture is one that places a great deal of emphasis on technology; for example, we strive to make the surface and assembly functions excellent while also ensuring they are user-friendly.\" That’s why we recruit the best talents to fully leverage their creativity. In the CAD industry, the requirements for developers are extremely high; one must possess three skills: first, a strong command of mathematics; second, expertise in computer graphics; and third, advanced skills in data handling and database management. As a result, it is difficult to find people worldwide who have all three of these skills. That’s why our R&D centers are located in the places with the best CAD development talent around the world, such as Russia, Hangzhou in China, Cambridge in the UK, India, and the United States. ” For over a decade, SolidWorks has been focused solely on developing and innovating to meet customer needs, continuously improving its products based on customer feedback. SolidWorks does not pursue a strategy of being all-inclusive; instead, it focuses on building strong partnerships. It has developed more than 600 partners around the world, each of whom possesses its own unique strengths. SolidWorks brings these partners together to create a win-win \"community\". “More than a decade ago, when this company was founded, we realized that research and development was our strength. Therefore, over the past ten years the company has never deviated from this approach: it has never engaged in direct sales, relying instead on agency and channel sales. Therefore, the entire company culture and organizational structure are built around the customer and channel marketing as their core. Through this model, the customer base is covered extensively and effectively. We place great emphasis on the training of our channels and agents; their professional skills and technical expertise are ultimately crucial for both their own success and the success of our company. We have great confidence in our agents, which is why we don’t have a direct sales team. We’re not concerned about competing with our manufacturer, and as a result, they are willing to treat this as a long-term business, focusing on developing their own technical and sales teams. ”John McEleney has a very clear vision for the company’s development; he places great emphasis on doing what one is good at and on fostering the widest possible level of cooperation. Through relentless efforts in product positioning, product development, and channel building, SolidWorks has achieved steady and rapid growth. (The above content is officially reproduced.) I just want to find out personally which software is more suitable for mechanical design! Although it has its advantages. (I hope everyone can give some feedback.)
