But non-professionals generally don't need it.

So none of the people above answered correctly. They've only heard of or used 3dmax, so it's this.

The function of 3dmax can be easily realized by catia, but the function of catia is not at all.

The mechanical design is designed by catia proe ug, which can be used for physical production.

Catia automobile and aircraft manufacturing industry has the most powerful function of cadcaecam.

At present, there are dozens of software optical modules with the most functions, which can realize electronic prototype modeling design, motion simulation, simple finite element analysis, mold design and even circuit diagram, wiring, factory layout and other modules. A complete Boeing 777 can be designed without drawing by catia. What do you think of the function of catia?

Ug is also used in automobile industry.

Proe auto parts industry uses many small products.

Pure industrial design only looks at the appearance of 3dmax, and uses more game characters, etc., but the works made by 3dmax cannot be used for mechanical design and processing, but can only be virtual things.

There is also a rhinoceros, that is, the rhinoceros cinema 4d, which is designed for styling. It seems that the rendering power is stronger.

Inventor also seems to be used in mechanical design.

Katia

CATIA is the flagship product development solution of Dassault France. As an important part of PLM collaborative solution, it can help manufacturers design their future products, and support all industrial design processes from pre-project stage, specific design, analysis, simulation, assembly to maintenance.

Modular CATIA series products are designed to meet the needs of customers in product development activities, including style and appearance design, mechanical design, equipment and system engineering, digital prototype management, processing, analysis and simulation. CATIA products are based on the open and extensible V5 architecture.

CATIA solution can shorten the development cycle and accelerate the response of enterprises to market demand by enabling enterprises to reuse product design knowledge. Since 1999, its digital prototype technology has been widely used in the market and become the most commonly used product development system in the world.

CATIA series products have become the main 3D design and simulation solutions in seven fields, such as automobile, aerospace, shipbuilding, workshop design, power and electronics, consumer goods and general machinery manufacturing.

CATIA's Advanced Hybrid Modeling Technology

Mixed modeling of design objects: In the design environment of CATIA, both entities and surfaces are truly interoperable;

Variable and parametric mixed modeling: In design, designers don't have to consider how to parameterize design objectives. CATIA provides variable-driven and post-parameterized functions.

Hybrid modeling of geometry and intelligent engineering: For an enterprise, many years of experience can be accumulated into the knowledge base of CATIA, which can be used to guide the novices of the enterprise, and can also be used to guide the development of new models and speed up the time to market of new models.

CATIA can be easily modified in the whole product cycle, especially in the later period.

Whether it is solid modeling or surface modeling, because CATIA provides an intelligent tree structure, users can modify products repeatedly conveniently and quickly, even if they need to make major modifications or update the original scheme in the final stage of design, it is very easy for CATIA.

All CATIA modules have complete correlation.

All modules of CATIA are based on a unified data platform, so all modules of CATIA are truly fully related. The modification of three-dimensional model can be fully embodied in two-dimensional, finite element analysis, mold and NC machining program.

The design environment of concurrent engineering greatly shortens the design cycle.

The multi-model working environment and hybrid modeling method provided by CATIA make concurrent engineering design pattern no longer a new concept. As long as the general design department issues the basic structural dimensions, the personnel of each subsystem can start to work, not only working together, but also participating in each other. Because of the interrelation between the models, the upstream design results can be used as a reference for the downstream, and the modification of the upstream design can directly affect the refreshing of the downstream work. Realize the real concurrent engineering design environment.

CATIA covers the whole process of product development.

CATIA provides complete design capabilities: from the conceptual design of products to the formation of final products, with its accurate and reliable solutions, it provides complete 2D, 3D and parametric hybrid modeling and data management means, from the design of individual parts to the establishment of final electronic prototypes; At the same time, as a fully integrated software system, CATIA organically combines mechanical design, engineering analysis and simulation, numerical control processing and CATweb network application solutions to provide users with a strict paperless working environment, especially the special modules for automobile and motorcycle industries in CATIA, which enables CATIA to have the widest professional coverage, thus helping customers shorten the design and production cycle, improve product quality and reduce costs.

CATIA has a much more powerful surface design module than its competitors, so it is necessary to introduce:

1. Universal shape design, GSD, generative modeling, a very complete curve manipulation tool and the most basic surface construction tool. In addition to all curve operations, it can also complete functions such as stretching, rotating, scanning, boundary filling, bridging, repairing fragments, splicing, concavo-convex, cutting, smoothing, projection and advanced projection, chamfering and so on. , continuity can reach G2 to generate closure. Fully parameterized operation.

2. Freestyle surface, FSS, freestyle modeling, almost completely nonparametric. In addition to all the functions of GSD, it can also complete surface control points (control points and deformation can be adjusted synchronously from multiple surfaces to the whole product shape), freely constrain boundaries, remove parameters, realize surface bridging, chamfering and fairing of automobile A surface standard. All commands can reach G2 very easily. With GSD and FSS, CATIA's surface function has surpassed all CAD software, even UG NX, which is also a competitor of the automobile industry.

3. Automobile Class A, ACA and automobile Class A surfaces are completely nonparametric. This module provides powerful curve and surface editing function and extremely powerful one-button surface smoothing function. Almost all commands can reach G3 without destroying the original smooth shape. It can realize synchronous surface operations (control point dragging, smoothing, chamfering, etc.). ) or even the entire product shape. For Toyota and others, the requirements for A-level surfaces are almost crazy (G3 is continuous, etc. ), they can also cope with it freely. At present, only pure modeling software such as Alias and Rinho can reach this height, but it can't reach the high accuracy of CATIA.

4.FreeStyle Sketch Tracer, FST, freestyle sketch drawing, which can draw the basic shape curve according to the three views or photos of the product.

5. Digital shape editor, DSE, digital surface editor, sampling, editing and cutting according to the input point cloud data, which meets the requirements of the closest product shape and can generate high-quality mesh triangles. Totally irrelevant.

6. Rapid surface reconstruction, rapid surface reconstruction, which provides a variety of ways to model the surface according to the input point cloud data or the curve generated by the small triangle after mesh division, which is completely nonparametric.

7.Shape Sculpter, which can edit the shape of a small triangle and perform various operations on the small triangle, is almost as powerful as CATIA surface operation, and is completely nonparametric.

8. BIW fastening, BIW fastening, welding mode and welding geometry design between BIW sheet metal parts.

9. Images and images. Shapes can be dragged, stretched, twisted and added with "plasticine blocks" like plasticine to achieve the ideal design shape. The conceptual design of product shape can be completed quickly.

1~9 is included in the shape design &; Modeling module

10. Healing Assistant, an extremely powerful surface repair tool, can automatically find and repair various broken surface defects.

All parts and assemblies of Boeing 777 except the engine are completely CATIA V4, and completely paperless office has been successfully realized from conceptual design to final debugging and operation. Visible CATIA's power.

CATIA V4 can only run on IBM's Unix graphics workstation. In order to run on various graphics workstation platforms and PCs more generally, V5 was born, which includes server-workstation version and stand-alone node version. Workstation version can run on various graphics workstations and Windows or UNIX operating systems (not under Linux), and stand-alone version can run on PC, notebook, Windows or other operating systems. The very pleasing software interface is simpler and more powerful than V4, which makes CATIA V5 become the reason why Ford, Toyota and other companies turn to CATIA, while Volkswagen, Dyke, Peugeot Citroen and other companies also spare no effort to turn from V4 platform to V5.

CATIA's competitors are UG NX, Pro/E, Topsolid and Cinmatron. Among them, NX, Pro/E and CATIA can be described as three points in the world. At present, CATIA occupies the largest market share in the field of design and engineering software. This comes from its strong customer source and military background. Compared with competitors, CATIA has the advantages of pleasing interface, powerful functions, strong functional support in special industries such as automobiles, aerospace and shipbuilding, and global sales cooperation of IBM, the leading IT company. Another important point is the support of Dassault Systemes from CATIA's parent company Dassault Systemes and other brother softwares:

1. Delmia, a powerful product line planning and management software, cooperates with Catia to complete the manufacturing feasibility analysis and implementation;

2.Inovia, a powerful data management and design support system.

3.Smarteam is a powerful PLM software, which ranks with UGS Team Center as the most successful software and the originator of PLM.

4.VPM, design a data sharing platform for design centers of multinational companies to share data and information status.

5. Solidworks, the ruler of 3D engineering software in the global mid-range market, became a signature weapon against other mid-range software after being acquired by Dassault, which effectively supported the penetration of high-end software CATIA in the low-end market.

6.Abaqus is one of the most powerful finite element software, which has the advantages of nonlinear, dynamic and implicit calculation. It has become an effective tool to effectively solve complex problems in automobile and aerospace fields, and ranks as the second giant of high-end CAE software along with LS-DYNA.

The history of Catia

CATIA is the abbreviation of English computer-aided three-dimensional interface application. It is the mainstream CAD/CAE/CAM integrated software in the world. In 1970s, Dassault Aviation became the first user, and CATIA came into being. From 1982 to 1988, CATIA released version 1, version 2 and version 3, and released version 4 with powerful functions in 1993. Now CATIA software is divided into two series: version 4 and version 5. Version V4 is suitable for UNIX platforms, and version V5 is suitable for UNIX and Windows platforms. The development of V5 version started at 1994. In order to make the software easy to learn and use, dassault systemes began to redevelop a brand-new version of CATIA V5 in 1994. The new version V5 has a more friendly interface and increasingly powerful functions, creating a new style of CAD/CAE/CAM software.

Dassault Air France is a world-famous aerospace enterprise. Its products are most famous for Mirage 2000 and rafale fighter. Dassault systemes, the product developer of CATIA, was founded in 198 1.

CATIA V5 customers can make full use of CATIA V4 mature follow-up application products to form a complete product development environment.

Aerospace:

CATIA originated from the aerospace industry and is the undisputed leader in the industry. With its accuracy, safety and reliability, it can meet various application requirements in the fields of commerce, national defense and aerospace. CATIA has been used to develop virtual prototypes in many projects of aerospace industry, including Boeing 777 and Boeing 737 of Boeing Aircraft Company (USA), rafale fighter of Dassault Aircraft Company (France), Global Express business jet of Bombardier Aircraft Company (Canada) and Dark Star unmanned reconnaissance aircraft of Lockheed Martin Aircraft Company (USA). In the Boeing 777 project, Boeing Aircraft Company used CATIA to design 100% mechanical parts except the engine. And 100% parts including engine are pre-assembled. Boeing 777 is also the only jumbo jet designed and assembled with 100% digitization. More than 1700 engineers, tooling designers, technicians and project managers participated in the Boeing 777 project, which was distributed in different regions of the United States, Japan and Britain. They are connected by 1, 400 sets of CATIA workstations and work in parallel. Boeing's designers modeled all the parts of the 777 in three dimensions, and pre-assembled the whole 777 in full size on the computer. Pre-assembly makes it unnecessary for engineers to make physical prototypes, and engineers can check and modify the interference and disharmony in the design on the pre-assembled digital prototypes. Boeing Aircraft Company announced that in the 777 project, compared with the traditional design and assembly process, due to the application of CATIA, 50% repetitive work and error modification time were saved. Although the research and development time of the first 777 is not very significant compared with other models with traditional design process, Boeing Aircraft Company predicts that the research and development of subsequent 777 models will save at least 50% time. The post-parametric processing function of CATIA also shows its superiority and powerful function in the design of 777. In order to meet the needs of special users, using the parametric design of CATIA, Boeing can get an electronic prototype that meets the needs of users without redesigning and establishing a physical prototype, and users can preview it on the computer.

Automobile industry:

CATIA is the de facto standard in the automotive industry and the core system used by the top automobile manufacturers in Europe, North America and Asia. CATIA has unique advantages in styling style, body and engine design, and provides end-to-end solutions for the design and manufacture of various vehicles. CATIA involves three key areas: products, processes and people. CATIA's scalability and concurrent engineering capability can significantly shorten the time to market.

Formula One racing cars, sports cars, cars, trucks, commercial vehicles, trams, subway trains and high-speed trains can all be used as digital products in CATIA, and digital projects can be implemented in digital factories through digital processes. CATIA's technology is unparalleled in the field of automobile industry, and it has been recognized by auto parts suppliers all over the world. The recent purchasing decisions made by some famous automobile manufacturers, such as Renault, Toyota, Kaman, Volvo and Chrysler, are enough to prove the development trend of digital cars. Scania is the world's leading truck manufacturer, headquartered in Sweden. Its annual output of trucks exceeds 50,000. When other competitors' truck parts are still around 25,000, Scania has reduced truck parts by half with CATIA system. Now, Scania Company uses more analysis and simulation in the whole process of truck development to shorten the development cycle and improve the performance and maintainability of trucks. CATIA system is the main CAD/CAM system of Scania Company, which is used for the design of truck systems and parts. By applying these new design tools, such as stress analysis of generative parts of CATIA system in engine and body chassis department, and supporting reuse in development process, the company has achieved good return on investment. Now, in order to further improve the performance of products, Scania is pushing designers, analysts and inspection departments to cooperate more closely in the whole development process. This cooperative working mode can make Scania company more adaptable to the market, and at the same time, it can continuously accumulate product knowledge from physical prototypes and virtual digital prototypes.

Shipbuilding industry:

CATIA provides excellent solutions for shipbuilding industry, including professional hull products, on-board equipment and mechanical solutions. Hull design solutions have been applied to many shipbuilding enterprises, such as General Dynamics, Meyer and Delta Marin, involving the design, manufacture and assembly of all types of ships. The structural design and definition of hull is based on three-dimensional parametric model. Parametric management of the relationship between parts and the changes of related parts can affect the appearance of the hull. The hull design solution is fully integrated with other CATIA products. Traditional CATIA solid and surface modeling functions are used for basic design and hull fairing. With GSM (Generative Design) as the parametric engine, Bath Iron Works carried out the conceptual design of destroyers and exchanged data with other ship structural design schemes.

CATIA version provides direct integration with Deneb machining, and is developed in cooperation with Fincantieri. The robot can process straight weld and arc weld, which overcomes the bottleneck of robot automatic line programming.

General Power Electric Ship and Newport News Shipbuilding Company used CATIA to design and build a new Virginia-class attack submarine of the US Navy. A large number of systems, from nuclear reactors and related safety equipment to all life support equipment, need a comprehensive and effective product data management system (PDM) to manage the definition of the whole submarine product, not just a bill of materials, but all three-dimensional digital products and welding equipment. ENOVIA provides powerful data management functions.

Meyer Werft's application of CAD technology has always been in the leading position in the industry, from design, parts, shipboard equipment to trial operation, involving all aspects of shipbuilding industry. Three-dimensional design and demonstration of all products have been completed before cutting the first steel plate.

In the process of ship design and manufacture, Delta Marin designs bridges, decks and propulsion systems according to the hull. Ship owners use the 4D rover to browse and check.

CATIA has also been successfully applied in China Guangzhou Wenchong Shipyard. CATIA is used for 3D design instead of traditional 2D design.

Workshop design:

On the basis of rich experience, IBM and Dassault-Systems have developed a new generation of solutions for shipbuilding, power plants, processing plants and engineering and construction companies. Including pipes, equipment, structures and automation documents. CCPlant is the first object-oriented knowledge engineering system in these industries.

CCPlant has been successfully applied to Chrysler and its extension enterprises. The design of Toledo jeep factory under construction was modified by using CCPlant and Deneb simulation. Cost savings have been clearly reflected. And it has a far-reaching impact on the operation of enterprises in the future.

Harden International's painting production line is mainly used in automobile and aerospace industries. Hayden International applied CATIA to design its advanced painting production line, and CCPlant significantly shortened the design and installation time. Shell has developed a new production process in Rotterdam by using CCPlant, with an annual processing capacity of 20 million tons of crude oil, which can produce a variety of complex chemical products such as plastics, resins and rubber.

Machining and assembly:

It is not enough for a product to have design, but also to have manufacturing. CATIA is good at 2D/ 3D correlation, analysis and NC machining of prisms and tool parts. The hybrid modeling scheme driven by CATIA rules ensures the high-speed production and assembly of precision products such as machine tools, medical instruments, offset press clocks and factory equipment to be successful at one time.

In the machine tool industry, users require products to be manufactured and assembled quickly and accurately. The powerful functions of dassault systemes products make them widely used in product design and manufacturing. Big manufacturers like Staubli have benefited a lot from dassault systemes products. Staubli uses CATIA to design and manufacture textile machinery and robots. Gideon Lewis used CATIA to design and manufacture large machine tools.

Dassault systemes products are also used in many small businesses. Like Klipan, CATIA is used to design and produce electronic terminals and control equipment of power stations. Polynorm uses CATIA to design and manufacture pressure equipment. Tweko uses CADAM to design welding and cutting tools.

Consumer goods:

Consumer goods companies all over the world trust CATIA, partly because the products designed by CATIA have novel styles, modeling tools and high-quality rendering tools. CATIA is used to design and manufacture the following products: tableware, computers, kitchen equipment, televisions and radios, and yard equipment.

In addition, in order to verify the consistency of a new concept in aesthetics and style selection, CATIA can generate realistic rendered photos from digitally defined products. Before the real product is produced, it can promote the sales of the product.
