summary This paper describes `Quick-sketch', a 2D and 3D modelling tool for pen-based computers. Users of this system define a model by simple pen strokes, drawn directlyon the screen of a pen-based PC. Exact shapes and geometric relationships are interpreted from the sketch. The system can also be used to sketch 3D solid objects andB-spline surfaces. These objects may be refined by defining 2D and 3D geometric constraints. A novel graph-based constraint solver is used to establish the geometricrelationships, or to maintain them when manipulating the objects interactively. The approach presented here is a first step towards a conceptual design system.Quick-sketch can be used as a hand sketching front-end to more sophisticated modelling, rendering or animation systems.
