Abstract

Despite the importance of the early design phase, designers still lack computer support in rapidly modelling their form concepts in Computer-Aided Design (CAD) systems due to the rigid User-Interface. Owing to its efficacy in instantly capturing ideas, traditional pen-and-paper sketching is still very popular amongst designers to record their concepts not only inside but also outside their office. This paper reports the ongoing research aimed at developing a portable, sketch-based tool allowing designers to obtain and share 3D CAD models on cameraphones directly from paper sketches. More specifically, the focus is on a prescribed sketching alphabet required to create a seamless link between sketching and CAD. Results of semi-structured interviews carried out with various design practitioners contribute important insights into the alphabet suitability. Further, the results and an implemented tool indicate that a sketching language based on this alphabet will be beneficial for designers, especially in a collaborative design environment.
