We present Sketch It, Make It (SIMI), a tool for designing precise models for rapid fabrication. SIMI provides a novel recognition and disambiguation architecture that supports designers in using pen-based interaction techniques without requiring users to enter persistent modes. The suite of pen-based interaction techniques let the designer fluidly transition from rough ideas to precise output within a single tool. These techniques are creating geometry, issuing gestures that edit the model, and for creating, enforcing, and maintaining geometric constraints. The architecture demonstrated in this system could be applied more broadly in other domains, including 3D modeling or graphic design.
