Starting with the customer’s brief, styling research prepares freehand sketches and drafts both for the interiors and exteriors, showing the positions of the vehicle’s various components. The research study continues with the development of 3D proposals using software such as ALIAS, ICEM and MAYA; these three-dimensional virtual models, which also allow animations, interactive management and full scale moving simulations, are used to directly produce the styling models by means of numerical control millers that process the virtual surface data through CAM applications.
