In the CAS/CAD field, the increasing adoption of Spline-based free-form methods to generate surfaces, has introduced a higher degree of freedom into the design process. However, on the other hand, this evolution has made the process of creating and manipulating surfaces more complex. For this reason a much more intuitive and intelligent task-centered and user-centered interaction paradigm is required. This paper presents a responsive interaction technique which adopts a sketch-based interface capable of exploiting the stepwise refinement process typical of conceptual designing. Further it makes use of adaptive user modeling techniques by introducing an innovative adaptive decision-tree structure for top-down designing. We illustrate the implementation of the algorithm and we highlight its efficiency and feasibility for its adoption within Sketch-Based Modeling Systems (SBMS).
