Surface engineering is the discipline that deals with connecting artistic designers to actual production. Turning conceptual drawings into real quality products requires complicated work using CAD software. Thanks to the analysis and rendering tools provided by the software, the designer is able to evaluate the quality of the designed surface, even before it is produced, drastically reducing prototyping costs. The experience gained in the automotive sector, in which the quality standard is certainly expressed at the highest level, allows us to design complex shapes with even very tight tolerances. Romano Gaspari Design Division makes surface modeling its strong point, providing mathematics for the creation of class A or class B products, depending on the materials and the type of production.
