The way of automotive 3-D styling based on digital hand sketching

This paper has investigated the approaches of automotive 3-D styling based on the hand sketching with Wacom^® Cintiq 21UX digital screen. By the analysis of curve modeling tools for the current CAD systems used broadly in automotive industry, the easier, more intuitive and more convenient 3-D styling approaches are discussed. The stylist can change the curves with modified strokes during the sketching in a natural way of painting. The combination of strokes can be achieved automotively. Some features are also proposed to realise those approaches.
