The main goal of the styling system is to provide the user an easy to use interface hiding the inherent mathematic nature of CAD. Creating rough 3D sketches should literally be as intuitive as 2D sketching with pen and paper. To achieve this, the tools developed in our system benefit from the stylists' skills, acquired through training over time. This paper focuses on the stroke-input methods of our styling system. We present different techniques for creating and modifying 3D curves: stroke splitting, oversketching and taping. In addition we report on the viability of using input constraints in immersive environments to overcome inherent weaknesses.encomputer aided styling (CAS)design processsketching006conference paper
