In recent years, with the support of governments at all levels and the support of the industry, the domestic software industry has achieved leap-forward development through independent research and development and innovation. A number of software companies with competitive competitiveness have emerged, breaking the long-term of foreign software companies. Monopolize the situation in the domestic market. In the field of CAD, the emerging power represented by Zhongwang CAD is quickly applied to all walks of life and develops together with many national enterprises.
Hudong Zhonghua Shipbuilding (Group) Co., Ltd. (hereinafter referred to as “Hudong Zhonghuaâ€) is a core enterprise of China State Shipbuilding Corporation. The products are constructed to cover multi-type military ships, ultra-large LNG carriers, ultra-large container ships and finished products. Hundreds of ship types, such as oil tankers, crude oil ships, bulk carriers, and special ships, as well as marine engineering and super-large steel structure engineering products, are among the most powerful shipbuilding enterprises in China. Its self-developed SPD shipbuilding design system has been applied in more than 200 enterprises and research institutes across the country. It has successively obtained the example of national defense technology industrial technology innovation, the 2012 Shanghai “quality benchmarkâ€, and the new China 60 years. Honorary awards such as the famous ship.

The rise of domestic CAD, breaking the monopoly of foreign CAD software
In the 1980s and 1990s, Hudong Zhonghua decided to purchase CAD industrial design software to enhance its competitiveness by coping with fierce competition from worldwide markets. At that time, Hudong Zhonghua chose to use foreign CAD software , and it was used for a long time, until it came into contact with Zhongwang CAD.
"Improving the national production of shipbuilding software " is Su Wenrong, the director of Hudong Zhonghua Information Research Institute, his lifelong wish. During the interview and exchange process, the director of the company with more than 30 years of experience in software application and development in the shipbuilding industry pointed out that with the significant increase in the demand for information technology in the “Digital Shipbuilding†strategy of Hudong Zhonghua, foreign CAD software is satisfied. The shortcomings in this demand are increasingly apparent: on the one hand, foreign software solves the problem of slow use of Chinese users, and its restrictions on secondary development interfaces impose constraints on the development of secondary development technology of Hudong Zhonghua on the CAD platform. On the other hand, foreign software vendors have brought cost increases to Hudong Zhonghua by virtue of its market monopoly position, high prices and strict upgrading policies. In addition, shipbuilding technology is a manifestation of a national military secret and national strength. Long-term dependence on foreign software will also bring the risk of revealing state secrets.
Director Su said that the rise of domestic CAD software represented by Zhongwang has gradually broken the monopoly of foreign software from the aspects of domestic users' localized services, open cooperation mode and R&D level support. He also believes that Zhongwang CAD is the leader of domestic software , capable of carrying and meeting the design needs of the shipbuilding industry.
Deep cooperation, creating a new situation in the national shipbuilding software
According to reports, based on more than 30 years of CAD/CAM software application and development experience, Hudong Zhonghua developed a Shipbuilding 3D CAD/CAM design system SPD (Ship Product Design) based on CAD platform in 2005. At present, the function of the SPD system has reached and partially surpassed the foreign similar systems, reaching the international advanced level. In order to completely get rid of the limitations of foreign CAD software technology restrictions on the continuous progress of SPD, in 2009, Hudong Zhonghua officially and in-depth cooperation with Zhongwang CAD, the ship professional software was successfully transplanted to the Zhongwang CAD platform, and continued R&D innovation.
“In addition to the stable performance of the software itself, reasonable price and local service advantages, Hudong Zhonghua is more interested in the possibility of deep cooperation brought about by the continuous optimization of the secondary development interface of Zhongzhong CAD!†Director Su clearly stated , in the hope that the software is one of the few to achieve "open code level," the software business joint ventures. “In-depth cooperation based on source code level is an important foundation for building a nationwide shipbuilding design solution.†According to Director Su, Hudong Zhonghua and Zhongwang’s goal in “National CAD Platform + SPD Shipbuilding Design Software †The agreement was reached and the two sides kicked off the strategic cooperation.

Continuous innovation, cooperation and win-win new development
Information construction is an inevitable requirement of market development. According to reports, Hudong Zhonghua's informatization construction has gone through the development stage from CAPP/CAM to CAD, from the initial stage of establishing MIS to the establishment of product electronic information model to achieve parallel design and gradually apply CIM technology. At present, it is accelerating in accordance with the concept and model of digital shipbuilding.
“With the transformation of traditional shipbuilding mode to modern shipbuilding mode, value and benefit are a long-term development process, and long-term virtuous circle will gain greater value.†Director Su pointed out that it is this choice The "key" of the process. In the process of cooperation between the two parties, the technical service team of Zhongwang CAD, and even the R&D team and Hudong Zhonghua actively communicated and returned, not only helping engineers to solve problems quickly, improving design efficiency, but also on SPD based on Zhongwang CAD platform. Software development provides corresponding support. This seems to be "a benign interaction between Hudong Zhonghua and will promote mutual progress."
In 2010, Zhongwang Software launched Zhongwang 3D with independent intellectual property rights. Through full understanding and experience, Hudong Zhonghua believes that Zhongwang 3D has great value in optimizing the design and manufacture of SPD in hull design and manufacturing in surface design and large-scale assembly. After deep communication and evaluation, the new round in three dimensions The cooperation also started.
After the compilation: Thanks to the forward-looking nature of Hudong Zhonghua's corporate strategy and the deep-open cooperation strategy of Zhongwang CAD, the development and application of the “Zhongwang CAD Platform+SPD†produced by the country broke the monopoly of foreign software and promoted the digitization of the industry. The development of shipbuilding technology. At present, this nationalized software portfolio has been widely used in the shipbuilding industry. With a number of well-known enterprises such as Guangzhou Wenchuan and Jiangnan Shipyard successfully applying SPD for ship project design and manufacture, we have reason to believe that the national shipbuilding design of shipbuilding software represented by “Zhongwang CAD Platform+SPD Professional Application†The power of the new model is being proven and highlighted.
