Introduction
CATIA is the flagship product development solution of French company Dassault. As an important component of PLM collaborative solutions, it can assist manufacturers in designing their future products through modeling and support all industrial design processes from pre project stages, specific design, analysis, simulation, assembly to maintenance.
Products and services
The modular CATIA series products provide product style and appearance design, mechanical design, equipment and system engineering, management of digital prototypes, mechanical processing, analysis, and simulation. CATIA products are based on an open and scalable V5 architecture.
By enabling enterprises to reuse product design knowledge and shorten development cycles, CATIA solutions accelerate the response of enterprises to market demands. Since 1999, its digital prototype process has been widely adopted in the market, making it the most commonly used product development system in the world.
The CATIA series of products provides 3D design and simulation solutions in eight major fields: automotive, aerospace, shipbuilding, factory design (mainly steel structures), architecture, power and electronics, consumer goods, and general machinery manufacturing.
Core technology
CATIA Advanced Hybrid Modeling Technology
Hybrid modeling of design objects: In the CATIA design environment, both solid and surface operations are truly interactive;
Mixed modeling of variables and parameterization: During design, designers do not have to consider how to parameterize design goals. CATIA provides variable driven and post parameterization capabilities.
Hybrid modeling of geometry and intelligent engineering: For an enterprise, years of experience can be accumulated in CATIA's knowledge base to guide beginners or guide the development of new models, accelerating the time for new models to be launched into the market.
CATIA has convenient modification capabilities throughout the entire product cycle, especially in the later stages of modification
Whether it is solid modeling or surface modeling, CATIA provides an intelligent tree structure, allowing users to easily and quickly make repeated modifications to the product. Even if significant modifications are needed in the final stage of design or updates to the original plan, it is very easy for CATIA.
All modules of CATIA have full correlation
The various modules of CATIA are based on a unified data platform, so each module of CATIA has true full correlation. The modification of 3D models can be fully reflected in the programs of 2D models, simulation analysis, molds, and CNC machining.
The design environment of concurrent engineering greatly shortens the design cycle
The multi model linked working environment and hybrid modeling approach provided by CATIA make the concurrent engineering design pattern no longer a new concept. As long as the overall design department distributes the basic structural dimensions, personnel from each subsystem can start working, which can work together without being intertwined; Due to the interconnectedness between models, the upstream design results can serve as a reference for the downstream, and the modifications made by the upstream can directly affect the refresh of downstream work. Implement a true concurrent engineering design environment.
CATIA covers the entire process of product development
CATIA provides comprehensive design capabilities: from conceptual design of products to the formation of final products, with its precise and reliable solutions, it provides complete 2D, 3D, parametric hybrid modeling and data management methods, from the design of individual parts to the establishment of final electronic prototypes; Meanwhile, as a fully integrated software system, CATIA organically combines mechanical design, engineering analysis and simulation, CNC machining, and CATweb application solutions to provide users with a rigorous paperless working environment, especially the specialized modules in CATIA for the automotive and motorcycle industries.
Functions and modules
Surface design module
CATIA has a powerful surface design module.
1.Generative Shape Design
GSD, abbreviated as Generative Modeling, is a very complete curve operation tool and the most basic surface construction tool. In addition to completing all curve operations, it can also perform functions such as stretching, rotating, scanning, boundary filling, bridging, patching fragments, splicing, convex points, cropping, smoothing, projection and advanced projection, chamfering, etc., with a maximum continuity of G2, generating a closed volume, Fully achieve the surface modeling function of ordinary 3D CAD software, such as Pro/E. Fully parameterized operation.
2.Free Style Surface
Abbreviated as FSS, it has a free style design and is almost completely non parametric. In addition to all the functions in GSD, it can also complete functions such as surface control points (which can achieve synchronous adjustment of control points and deformation from multiple surfaces to the entire product appearance), free constraint boundaries, removal of parameters, and surface bridging, chamfering, smoothing, etc. that meet the standards of automotive A-surface. All commands can easily reach G2.
3.Automotive Class A
Abbreviated as ACA, it is a Class A automotive surface that is completely non parametric. This module provides powerful curve and surface editing functions, as well as incredibly powerful one click surface smoothing functions. Almost all commands can reach G3 without damaging the original smooth shape. It can achieve synchronous surface operations (control point dragging, smoothing, chamfering, etc.) on multiple surfaces or even the entire product shape.
4.FreeStyle Sketch Tracer
Referred to as FST, it is a free style sketch drawing that can trace the basic shape curve of the product based on three views or photos.
5.Digitized Shape Editor
Referred to as DSE, a digital surface editor, which samples, edits, and trims the input point cloud data to meet the requirements of the closest product appearance, and can generate high-quality mesh small triangles. Completely non parametric.
6.Quick Surface Reconstruction
Referred to as QSR, rapid surface reconstruction provides various ways to generate curves for surface modeling based on input point cloud data or mesh generated small triangles, completely non parametric.
7.Shape Sculpter
The shape editing of small triangular bodies allows for various operations on them, with almost powerful functions similar to CATIA surface operations and completely non parametric.
8.Automotive BIW Fastening
Design the welding method and geometric dimensions between the various sheet metal parts of the car's white body for fastening.
9.Image & Shape
You can drag, stretch, twist the product shape, add "Image Shape" and other methods like pinching dough to achieve the ideal design shape. Can extremely quickly complete the conceptual design of product appearance.

10.Healing Assistant
An extremely powerful surface sewing tool that can automatically identify and repair various surface defects.
