To improve the efficiency and naturalness of computeraided design (CAD), this paper introduces a new design paradigm in which a highly interactive sketch-based user interface and a design-knowledge reuse based on retrieval are combined seamlessly. Freehand sketching serves as a cognitive tool to support users' intuitive abilities by exploring the visual components of a design. Design knowledge reuse is achieved by searching the similar designs in an existing library. To demonstrate the validity

They both use the same key components: sketch beautification module, a constraint solver, a 2D&3D search engine and a sketch-based user interface. The preliminary usability evaluation shows that our proposed design paradigm is more natural for usage and has higher efficiency than the traditional CAD systems.
