Driving Innovation in Various Industries, Leading to the Development of New Technologies and Products

## (CATIA Mechanical Engineering Rich Text)Design and Validate All Kinds of Products

As products and experiences continue to increase in complexity, performance and quality targets are becoming more demanding. CATIA answers that challenge, enabling the rapid development of high-quality mechanical products.

Mechanical engineers equipped with CATIA 3D Modeling tools can gain insight into key factors of quality and performance early in the product development phase. Digital prototyping, combined with digital analysis and simulation, allows product development teams to virtually create and analyze a mechanical product in its operating environment.

**CATIA Mechanical Engineering** provides the platform which enables engineers to create any type of 3D assembly, for a wide range of engineering processes.

## (CATIA Mechanical Engineering Highlight 1)Engineering software programs in a seamless Environment

With traditional PDM or PLM, checking data in and out takes so long, many engineers delay it. Then engineers waste hours comparing outdated versions and consolidating changes.

**3D**EXPERIENCE CATIA [integrates PLM](https://www.3ds.com/products/product-lifecycle-management), so engineers never leave the design environment. With **3D**EXPERIENCE CATIA, everyone sees model updates in real-time. Plus, since it isn’t file-based, no one wastes time checking files in and out.
It also manages component families to configure designs. When a component changes, the "where used" function identifies which subassembly or assembly used it.

## (CATIA Mechanical Engineering Highlight 2)CATIA is the Best Geometrical Core Modeler

CAD requires flexible, powerful modeling capabilities and digital models must accurately reflect reality. CATIA is known for its high geometric accuracy. It is so robust; engineers can quickly iterate without the model failing. Surfacing provides a competitive advantage from energy-efficient aerodynamic surfaces to cool-looking designs. Surfaces have no thickness, so they are easier to manipulate than solid geometry. You can create beautiful organic shapes and Class A surfaces.

Only CATIA combines highly accurate 3D solid modeling with Class A surfacing capabilities.

## ## (Mechanical Engineering) Start Your Journey

 We needed a CAD package that had the power to cope with the whole aircraft. We knew CATIA could do that. With this platform, very early on we could build a composite part using a composite workbench to build up the layers and plies. When there is more analysis being done, we can look at the best way to manufacture the part from start to finish; it is a far quicker process.
