CATIA's Advanced Hybrid Modeling Technology
Hybrid Modeling of Design Objects:
Hybrid Modeling of Design Objects:
Hybrid Modeling of Variables and Parameters:
Hybrid modeling of variables and parameters:
Designers don't have to think about how to parameterize their design targets when designing, but rather, CATIA provides both variable-driven and post-parameterization capabilities.
Mixed variable and parametric modeling: Designers don't have to think about how to parameterize their design goals at design time.
Hybrid Geometric and Intelligent Engineering Modeling: For a company, years of corporate experience can be accumulated into CATIA's knowledge base and used to guide novices in the organization, or to guide the development of new models, accelerating the time to market for new models.
CATIA has the ability to facilitate modifications throughout the product cycle, especially late modifiability
Whether it's solid modeling or surface modeling, because CATIA provides an intelligent tree structure, users can easily and quickly repeat the modification of the product, even if it is necessary to make major modifications in the final stages of the design, or an update of the original program, it is all easy for CATIA. For CATIA, it is all very easy.
All CATIA modules have full relevance
CATIA modules are based on a unified data platform, so there is true full relevance of all CATIA modules, and modifications to the 3D model are fully reflected in the 2D, as well as in the FEA, tooling, and CNC machining programs.
Parallel engineering design environment makes the design cycle greatly shortened
CATIA provides a multi-model linkage of the working environment and hybrid modeling, so that the parallel engineering design mode is no longer a new concept, the overall design department as long as the basic structure of the dimensions of the release, the sub-systems of the staff can begin to work, not only to collaborate on the work, but also do not implicate each other; due to the interconnectedness of the model, the model can be used to create a new model, the model can be used to create a new model. Due to the interconnectedness of the models, the upstream design results can be used as a reference for the downstream, and at the same time, the upstream modification of the design can directly affect the downstream work to refresh. Realizing a truly parallel engineering design environment.
CATIA covers the entire process of product development
CATIA provides complete design capabilities: from the conceptual design of a product to the formation of the final product, with its accurate and reliable solutions to provide a complete mix of 2D, 3D, parametric modeling and data management means, from the design of a single part to the establishment of the final electronic prototype; at the same time, as a fully integrated software system, CATIA can be used as a reference for downstream work. At the same time, as a fully integrated software system, CATIA will mechanical design, engineering analysis and simulation, CNC machining and CATweb network application solutions are organically combined together to provide users with a strict paperless working environment, especially for the automotive, motorcycle industry in CATIA's special module, so that CATIA has the widest professional coverage, thus helping customers to achieve the shortening of the design and production cycle, improve product quality and reduce costs. The CATIA system is designed to help customers shorten design and production cycles, improve product quality, and reduce costs.
CATIA has surface design modules that are far superior to those of its competitors, and it is necessary to introduce them here:
1. Generic Shape Design (GSD), a very complete curve manipulation tool and the most basic surface construction tool, in addition to the curve manipulation, can complete the stretch, rotation, scanning, boundary filling, bridging, repair, and so on. In addition to all the curve operations, it can do stretching, rotating, scanning, boundary filling, bridging, repairing fragments, splicing, bumping, cropping, smoothing, projection and advanced projection, chamfering, etc. The continuity is up to G2, and it generates a closed piece of volume, which is a complete parametric operation of the surface modeling functions of ordinary 3D CAD software, such as Pro/E.
2. Free Style Surface, FSS, is almost completely non-parametric. In addition to including all the functions of GSD, it can also accomplish such functions as surface control points (which can synchronize the adjustment of control points and deformation of polysurfaces to the entire product shape), free constraint boundaries, removing parameters, and reaching the automotive A-surface standard surface bridging, chamfering, and smoothing functions, all of which can be commanded to reach the G2 with great ease. With GSD and FSS, CATIA's surfacing capabilities have surpassed those of all CAD software, including UG NX, a competitor in the automotive industry.
3. Automotive Class A, ACA, is a fully non-referential surface module that provides powerful curve editing and one-click surface smoothing capabilities. Almost all commands can be used to achieve G3 without destroying the original smooth shape. Synchronized surface operations (control point dragging, smoothing, chamfering, etc.) can be performed on multiple surfaces or even the entire product profile. For Toyota and other companies that have crazy requirements for Class A surfaces (full G3 continuity, etc.), this program can handle it with ease. Currently, only pure modeling software like Alias, Rinho can reach this high level, but not to the high precision of CATIA.
4. FreeStyle Sketch Tracer, FST, free style sketching, can be based on the product's three views or photographs traced out the basic shape of the curve.
5. Digitized Shape Editor (DSE) is a digital surface editor that samples, edits, and cuts the input point cloud data to achieve the closest possible shape to the product, generating high-quality mesh triangles. Completely non-parametric.
6. Quick Surface Reconstruction, provides various ways to generate curves for surface modeling based on input point cloud data or small triangles after mesh.
7. Shape Sculpter, a shape editor for small triangles, allows you to perform a variety of operations on small triangles, almost as powerful as CATIA surface operations, and is completely non-referential.
8. Automotive BIW Fastening, automotive body-in-white fastening, design of the automotive body-in-white between the various sheet metal parts of the welding method and welding geometry.
9. Image & Shape, can be pinched like playdough drag, stretch, twist the product shape, add "playdough blocks" and other ways to achieve the ideal design shape. Can be extremely fast to complete the product shape concept design.
1~9 are included in the Shape design & Styling module
10. Healing Assistant, an extremely powerful surface mending tool, can automatically find and mend all kinds of broken surface defects.

Aerospace:
CATIA was born out of the aerospace industry and is the undisputed industry leader. It meets the needs of a wide variety of applications in the commercial, defense, and aerospace sectors with precision and safety, and reliability. CATIA has been used to develop virtual prototypes for a number of projects in the aerospace industry, including the Boeing 777 and Boeing 737 for Boeing Aircraft (USA), the Rafale fighter for Dassault Aviation (France), the Global Express business jet for Bombardier Aircraft (Canada), and the Lockheed Martin business jet for Lockheed Martin. For the Boeing 777, Boeing Aircraft used CATIA to design 100 percent of the mechanical parts except for the engine, and 100 percent of the mechanical parts, including the engine, were designed in CATIA. The Boeing 777 is the only large jetliner to date that has been 100% digitally designed and assembled. More than 1,700 engineers, tooling designers, technicians, and program managers were involved in the Boeing 777 project, located in the United States, Japan, and the United Kingdom. Connected by 1,400 CATIA workstations working in parallel, Boeing's designers modeled all of the 777's components in three-dimensional solid form and pre-assembled the entire 777 full-size on a computer. The pre-assembly eliminated the need to build a physical prototype, allowing engineers to check and modify interferences and inconsistencies in the design on a pre-assembled digital prototype.Boeing Aircraft announced that the application of CATIA saved 50 percent of the duplication of work and time spent on error corrections in the 777 program, compared to the traditional design and assembly process. Although the development time savings for the first 777 were not as dramatic as for other models using traditional design processes, Boeing Aircraft expects to save at least 50 percent in the development of the 777's successor. CATIA's post-parametric processing capabilities were also shown to be superior and powerful in the design of the 777. To meet the needs of special users, using CATIA's parametric design, Boeing did not have to redesign and build a physical prototype, but simply made parameter changes to get an electronic prototype that met the user's needs and that the user could preview on a computer.
Automotive industry:
CATIA is the de facto standard for the automotive industry, and is the core system used by top automakers in Europe, North America, and Asia. CATIA has unique strengths in styling, body, and engine design, and provides end-to-end solutions for the design and manufacture of a wide range of vehicles.

The structural design and definition of the hull is based on a 3D parametric model. Parameterization manages the correlation between parts, and changes to 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 capabilities are used for basic design and hull smoothing, and Bath Iron Works applies GSM (Generative Styling) as the parametric engine for conceptual design of the destroyer and data exchange with other ship structural design solutions.
CATIA version 4.2 provides direct integration with Deneb machining and has been developed in collaboration with Fincantieri to allow robots to machine straight and arc welds and overcome bottlenecks in robotic automated line programming.
General Dynamic Electric Boat and Newport News Shipbuilding used CATIA to design and build the U.S. Navy's new Virginia-class attack submarine. The large number of systems from the nuclear reactor, associated safety equipment, and all life support equipment required a comprehensive and effective product data management (PDM) system to manage the entire submarine product definition, not just a bill of materials, but all 3D digitized products and welding equipment.
Meyer Werft has been an industry leader in the use of CAD technology for all aspects of shipbuilding, from design, to parts, to onboard equipment, to commissioning. The entire product has been designed and demonstrated in 3D before the first steel plate is cut.
Delta Marin designs bridges, decks, and propulsion systems in accordance with the hull during the design and construction of a ship. The owner utilizes a 4D rover to navigate and inspect the ship.
Wenchong Shipyard in Guangzhou, China, also uses CATIA successfully. CATIA is used for 3D design, replacing the traditional 2D design.
Plant design:
Building on a wealth of experience, IBM and Dassault - Systems have developed a new generation of solutions for shipbuilders, power producers, processors and engineering and construction companies.
