The integration of the CATIA 3D software for several years now in our project planning has revolutionized the way we design, develop and undertake our projects as it is one of the most flexible applications for Innovative Product Design and Simulation. The leading CATIA 3D software offers a real competitive edge thanks to numerous and versatile features and a much better visualization offering all stakeholders a comprehensive look at the graphic design. It also allows incorporationof all of the elements of a project in a single model to better detect potential conflicting issues. Similarly, the software can be used to optimize the design and the calculations regarding components with complex structural geometry. CATIA 3D is an essential part of our customer tailored approach for achieving top performance.
