1.Pro/Engineer operating software is a three-dimensional integrated CAD/CAM/CAE software under PTC. Pro/Engineer software is famous for its parameterization. It is the earliest user of parametric technology and plays an important role in the field of 3D modeling software. As a new international standard in the field of mechanical CAD/CAE/CAM, Pro/Engineer has been recognized and popularized by the industry, and it is one of the mainstream CAD/CAM/CAE software, especially in the field of domestic product design. Pro/Engineer and WildFire are the software names used by PT, but there are many terms in the names used by domestic users, such as ProE, PROE/E, rags, etc. , all refer to Pro/Engineer software, proe200 1, proe2.0, proe3.0, proe4.0, proe5.0, CREO 65438+. Pro/E first put forward the concept of parametric design, and used a single database to solve the correlation problem of features. In addition, it adopts a modular way, and users can choose according to their own needs without installing all modules. Pro/E feature-based model can integrate the whole process from design to production, and realize concurrent engineering design. It is not only applicable to workstations, but also to stand-alone computers. Pro/E adopts modular mode, which can be used for sketch drawing, parts making, assembly design, sheet metal design, machining, etc., to ensure that users can choose and use according to their own needs.
2. Enterprises generally refer to legal persons or other social and economic organizations that use various factors of production (land, labor, capital, technology and entrepreneurial talents) to provide goods or services to the market in order to obtain profits, and implement independent operation, self-financing and independent accounting. In the category of commodity economy, as one of the various modes of organizational unit, according to certain organizational rules, an organic economic entity generally aims at profit, maximizing the interests of investors, customers, employees and the public, and exchanging income by providing products or services. It is the product of social development, and develops with the development of social division of labor. Enterprises are the main body of market economic activities; Under the socialist economic system, the coexistence of various enterprises constitutes the micro-foundation of the socialist market economy. Enterprises have three basic organizational forms: sole proprietorship, partnership and company, and corporate enterprise is the most important and typical organizational form in modern enterprises. Modern economic theory holds that enterprises are essentially "a mechanism of resource allocation", which can realize the optimal allocation of the whole social and economic resources and reduce the "transaction cost" of the whole society.
