Surface modelling, analysis and visualisation software developer ICEM Ltd claims South Korean SUV specialist SsangYong reduced the time needed to create the Class A surface data for the body and interior of the new Rexton by 60% through the use of its Surf software suite.

Although the Rexton was designed in Italy by Italdesign, SsangYong’s designers and engineers in Korea were responsible for developing the stylist’s requirements into the final Class A surface data required by the various manufacturing processes for the vehicle’s body and interior trim. They relied on the Surf product for this crucial design development process.

Starting from the ‘point cloud’ data generated by the 3D scanning of the stylist’s agreed clay model, the software was used throughout the design development and the generation of the Class A digital surface models of all the exterior and the principal interior components of the Rexton.

During the design development process, the digital mock-up and dynamic surface analysis facilities, such as highlights analysis and curvature analysis, were used extensively. These enabled the development team to reduce to a minimum the number of iterations required to arrive at the final Class A surfaces, while maintaining the original design intent. This Class A surface data was then exported to SsangYong’s Catia CAD/CAM system for use in the production tooling design process.

Son Jung-Sup, computer-aided design manager at SsangYong Motor, said: “ICEM Surf enabled us to reduce the time needed to complete the design development of the Rexton by some 60% compared with our previous methods. The quality of the final surface data was also improved.”

SsangYong has also used the ICEM software for design development work on other vehicles in the SsangYong range, including the Musso-Sports and the Chairman luxury saloon car.
