they feature the latest technology? The answer is because the brain processes subliminal information that is produced by the interaction of form and light. The exact smoothness of a smooth surface is defined by the technology used to design and produce it. Free- form surfaces, edges and curves designed using traditional CAD systems almost always have kinks or rough edges that are often only visible under particular lighting conditions or from certain viewing angles and impair the visual appearance of the final product. The best Class- A surface design tools act as a key interface between the design department and the car's engineering team. Developed in close collaboration with Class- A surfacing professionals, the comprehensive ICEM Shape Design suite of software solutions from Dassault Systems is used by a large number of leading car manufacturers and suppliers for the modeling of Class- A surfaces, making it a clear leader in this field. ICEM Shape Design enables mechanical designers, shape designers, and stylists to create, validate, and modify surfaces of any type, from exterior and interior trim to engine housings, particularly those which are visible and tangible to the end customer. No other surface design solution allows design professionals to create stunning surfaces of all types, as well as accurately measure and visualize the impact of individual changes to other parts of the design. No other surface design solution fits better within the all- encompassing product development environment. Class- A surfaces in CATIA Because Class- A surfaces cannot be developed solely in isolation, the integration with the virtual design environment is crucial to maximize efficiency, as well as the effectiveness of the entire product development process. The greater the emphasis manufacturers put on the development of Class- A surfaces, the closer design and engineering teams have to work together, making that integration more important. Without it, the resultant gaps in the development process chain lead to engineering headaches and expensive redesigns. ICEM Shape Design was the first Class- A surface modeling tool to be fully integrated into the CATIA virtual design environment, setting a new standard for Class- A modeling. Users can now work towards the surface quality required for end products throughout the entire development process within one system, and without converting or losing data.

Draftsmen and designers can develop their initial ideas in freeform on a computer as well as develop data models from 3D scans or earlier drafts. The modeler can then easily and intuitively adjust these drafts in CATIA. The 3D models generated can be used at any time for subsequent stages in the engineering process. Real- time designs In addition to the parallel use of drafts and the high surface quality of the end product in particular, the multiple analysis and modeling functions of ICEM Shape Design are crucial. If the geometry of the surface changes while working with ICEM Shape Design, the impact of the change is directly visible via advanced dynamic diagnosis capabilities. The surface modeler receives real- time notification about the quality and the visual appearance of the surface enabling them to make a judgment on the validity of the outcome in terms of surface quality and aesthetics. Lighting studies with different settings for the definition of light sources, reflectivity, and positioning of highlights provides a good example of this type of diagnosis. Thanks to associative geometry, these changes to the surface model are immediately available in CATIA. Using a single common data format from end to end - as opposed to different formats from standalone, incompatible systems - results in large time and cost savings. This integration covers the entire development process chain, allowing software- based development to minimize the reliance on clay models and standalone renderers in the early phases of development. Data can be shared with other applications for everything from crash analysis and tooling to product documentation. The progressive replacement of physical models, prototypes and materials with virtual equivalents offering the same level of accuracy allows faster, less expensive product feasibility testing. Ultimately, the above process allows greater freedom and flexibility for design professionals, and a faster, more efficient, and more cost-effective complete development process. more information? click here!
