We describe a program called SKETCHIT that transforms a single sketch of a mechanical device into multiple families of new designs. It represents each of these families with a "BEP-Model," a parametric model augmented with constraints that ensure the device produces the desired behavior. The program is based on qualitative configuration space (qc-space), a novel representation that captures mechanical behavior while abstracting away its implementation. The program employs a paradigm of abstraction and resynthesis: it abstracts the initial sketch into qc-space then maps from qc-space to new implementations.
