Developing a complex product is no longer solely about creating precise geometry. It also involves exploring alternatives, evaluating behaviour, coordinating disciplines, managing requirements, reducing environmental impact, and anticipating issues before manufacturing the first prototype.
With this new release of CATIA on the 3DEXPERIENCE platform, Dassault Systèmes reinforces precisely that comprehensive vision of product development. The new version incorporates enhancements in design and styling, mechanical engineering, composite materials, systems engineering, and construction, with a common denominator: leveraging the virtual model as a shared workspace to design, analyse, and make decisions.
Rather than being an update focused merely on new modelling commands, R2025x expands the possibilities for automation, optimisation, and collaboration within the 3DEXPERIENCE platform.
CATIA R2025x introduces new roles, applications, and capabilities, alongside enhancements to existing tools.
The main developments impact visual design automation, parametric optimisation, reverse engineering, eco-design, and greater integration between mechanics, electronics, and software. The following table summarises the most relevant new features of CATIA R2025x.

One of the clearest lines of evolution in CATIA R2025x is bringing the digital model closer to the physical product experience.
New mixed reality capabilities allow users to interact with three-dimensional models within a real-world environment. This offers designers and engineers a more direct perception of aspects such as proportions, ergonomics, visibility, or the layout of controls.
Instead of reviewing the design exclusively on a screen, the professional can step into the product’s context and evaluate it at scale. In sectors such as automotive, this capability facilitates, for example, cabin analysis, component accessibility, or the driver’s experience before a physical prototype is available.
Mixed reality does not replace CAD modelling; instead, it adds a new layer of validation. The model ceases to be solely a geometric representation and becomes an experience with which it is possible to interact.
The CATIA Visual Scripting application allows the creation of design processes using visual graphs, connecting operations and parameters without relying exclusively on traditional programming.
CATIA R2025x incorporates enhancements aimed at organising these graphs, interpreting data flows more clearly, and detecting warnings or errors in the different operators. It also allows the generation of video sequences with variations of a parametric model to observe how changes to each parameter influence the final result.
This capability proves particularly useful when the problem does not consist of obtaining a single geometry, but rather studying an entire family of solutions.
A designer can automatically vary dimensions, curvatures, clearances, or patterns, and compare the results without manually modifying each configuration. In this way, time spent on repetitive operations shifts towards analysing alternatives and choosing the most appropriate solution.
The version also pays close attention to intellectual property protection. Permission systems allow access control over design sequences when suppliers, partners, or external organisations are involved.
The quality of a visualisation does not depend solely on the result being attractive. In engineering and industrial design, a representation must help accurately assess materials, reflections, lighting, and finishes.
CATIA R2025x expands its capabilities through the Validation Rendering application, included in the Perceived Quality Engineer role. This solution provides a physically plausible simulation of lighting and a rendering workflow geared towards making reliable visual comparisons.
It can be used, for example, to evaluate the light distribution of a lamp, compare different surface finishes, or check how a material reacts under specific lighting conditions.
Added to this is the Stellar interactive rendering engine and its performance mode. This allows balancing physical accuracy with calculation speed to maintain fluid interaction even during demanding visualisation tasks.
Visualisation is thus integrated into the validation process. It is not limited to creating final images for a presentation. It becomes a tool for choosing between alternatives before manufacturing.
Reverse engineering typically begins with a point cloud or a mesh obtained through 3D scanning. The challenge lies in transforming that discretised information into editable CAD surfaces and features.
CATIA R2025x enhances the Reverse Engineer role with new smart reconstruction functions. To the existing capabilities for recovering mechanical geometries, a function aimed at reconstructing extrusion-based geometric characteristics is added, completing a semi-automated workflow to convert meshes into virtual models.
This can significantly reduce the manual work required to interpret a physical part. Instead of reconstructing each element from scratch, the system helps identify specific geometric characteristics and generate a usable CAD representation.
The enhancement is relevant for projects involving updates to legacy components, reproduction of parts without digital documentation, product inspection, or the adaptation of existing geometries.
The capabilities of ICEM Design Experience have also been updated, aimed at improving the quality of Class-A surfaces, their visual analysis, and model comparison. These surfaces are particularly important in sectors where continuity and exterior finish have a direct influence on product perception.
Generative design was already part of CATIA. In R2025x, the Structural Generative Designer role incorporates a new parametric shape optimisation capability applied to CAD models.
This role combines parametric and non-parametric optimisation techniques. The latter includes topology optimisation, in which the algorithm determines where it is appropriate to preserve or remove material within a design volume. In the new parametric shape optimisation, the system modifies variables already defined in the CAD model, such as thicknesses, radii, positions, lengths, or angles.
The difference between both approaches is significant. In conventional topology optimisation, the algorithm determines where it is necessary to keep or remove material within a design volume. In parametric optimisation, the system modifies dimensions and variables already defined in a CAD model: thicknesses, radii, positions, lengths, or angles, among others.
The ultimate goal is not simply to generate an organic shape, but to optimise a model that maintains its parametric logic and can continue to evolve within the design process.
This combination allows exploring more alternatives with fewer manual iterations. The engineer can define variables, constraints, and objectives, and use computation to identify configurations that improve structural performance or reduce weight.
Designing with composite materials requires managing plies, orientations, thicknesses, overlaps, and manufacturing processes. An apparently correct geometry can prove difficult to produce if ply-book limitations are not considered from the outset.
The new Composites Designer for Transportation and Mobility role aims to accelerate the design of composite components and improve coordination between the teams involved.
Its capabilities include more precise material management, improvements in ply calculation, and the automatic generation of reinforcements. The objective is to achieve more reliable laminates and maintain continuity between geometric definition and manufacturing.
This integration is particularly relevant in mobility and transport, where composites enable the development of lighter structures without sacrificing strength. However, their advantages depend on the design being compatible with a realistic manufacturing process.
Sustainability is also incorporated more directly into the virtual twin through the Eco-Design Engineer role.
CATIA R2025x expands the capability to perform Life Cycle Assessment (LCA) studies on a larger scale. Material composition and environmental data become part of the virtual representation of the product, allowing its footprint to be analysed during the design phase.
Rather than evaluating the environmental footprint only when the product is already defined, CATIA R2025x allows comparing materials, processes, or construction alternatives while there is still scope to modify them.
The automated allocation of human activities based on life cycle inventories also reduces the work required to prepare these studies. In this way, environmental analysis can be better integrated into standard engineering workflows rather than being an independent check at the end of the project.
Developing complex industrial products, such as vehicles, aircraft, machinery, or electronic devices, requires coordinating mechanics, electronics, and software. CATIA R2025x incorporates new capabilities to improve that collaboration and maintain traceability across disciplines.
The new Collaborative Circuit Board Designer role facilitates collaboration between electronic and mechanical design teams during the development of printed circuit boards.
Compatibility with the IDX V3 standard allows information exchange and change coordination between both environments. This early collaboration helps detect interferences between the board, its components, and the mechanical enclosure.
The development workflow can also rely on thermal, structural, and electromagnetic analyses within the multidisciplinary 3DEXPERIENCE environment.
R2025x also introduces traceability enhancements through new connectors with the platform’s cloud services. The goal is to manage larger datasets and more complex projects without losing the relationship between requirements, architecture, design, and implementation.
For its part, the new Magic Systems EE & Software Architect role provides specialised profiles and menus to define, visualise, and manage relationships between hardware architecture components within a single workspace.
The System Software Production Engineer role incorporates the capability to generate executable files directly from UML systems architecture models.
This capability automates part of the transition from the architecture model to its executable implementation, reducing certain manual tasks and shortening the workflow between design and implementation.
Meanwhile, Collaborative Designer for CATIA Magic improves change management and collaboration on systems models. It also allows generating a software work breakdown structure from the architecture, including support for agile epics and traceability towards implementation and testing.
These capabilities are especially important in complex products or those subject to certification, where designing each subsystem correctly is not enough. It is also necessary to demonstrate how requirements, decisions, components, and verifications relate to each other.
Cyber security can no longer be treated solely after product development. Connected systems need to incorporate threat analysis from their earliest stages.
The Magic Cyber Security Engineer role integrates with the MITRE ATT&CK libraries, used to describe known attack tactics and techniques. This connection helps identify potential vulnerabilities and incorporate mitigation measures within the system architecture.
In this way, security becomes part of the engineering model. Threats, risks, and protection measures can be linked to the functional elements of the system and remain traceable throughout its evolution.
Although CATIA is mainly associated with product engineering, R2025x also introduces enhancements for construction and civil engineering.
The Wall Sketcher tool incorporates new constraints to define walls with greater precision and perform modifications more agilely. The creation of openings in elements such as walls, columns, or concrete components is also improved.
The ability to configure custom object types for beams and columns allows the model to be adapted to the particular requirements of each project. At the same time, compatibility with IFC 4.3 improves information exchange, particularly in projects linked to road infrastructure.
In civil engineering, corridor alignment segmentation allows long linear elements to be divided into more manageable sections. This reduces the computational load and facilitates updates in road or extensive infrastructure projects.
The earthworks workflow also incorporates commands to perform local modifications without having to recalculate or redefine large parts of the model unnecessarily.
CATIA R2025x does not stop at expanding modelling functions. Its evolution points towards a platform where the virtual model brings together design, simulation, sustainability, systems, and construction.
Mixed reality and physically consistent rendering allow for a better evaluation of the product experience and appearance. Visual Scripting and parametric optimisation expand automation and the exploration of alternatives. New capabilities for composites, reverse engineering, and eco-design connect the model with manufacturing and the life cycle.
At the same time, integration between mechanics, electronics, and software improves the traceability of increasingly multidisciplinary products.
The result is an environment where designing no longer means simply defining geometry. It means building a virtual twin capable of supporting technical decisions from the first ideas through to implementation.
