This paper presents the system which enables a style designer to generate 3 dimensional free-form curve models in a computer easily as if he draws rough sketches on paper. The system consists of three modules; the user-interface module which enables a designer to draw rough sketches in the form of perspective projection directly on the display, the module to automatically recognize geometric and topological constraints on the rough sketches, and the module to calculate 3 dimensional points and free-form curves based on these constraints. The process of these modules can be quickly executed during the interaction of the designer with the computer. Finally some examples of the processing are shown, and efficiency of the system is evaluated. © 1993, The Japan Society for Precision Engineering. All rights reserved.
