Abstract
This chapter describes a program called SKETCHIT that transforms a single sketch of a mechanical device into multiple families of new designs. To "interpret" a sketch, the program first determines how the sketched device should have worked. The program then derives constraints on the geometry to ensure the device works that way. The program is based on qualitative configuration space (qc-space), a novel representation that captures mechanical behaviour while abstracting away the particular geometry used to depict this behaviour. The program employs a paradigm of abstraction and resynthesis: it abstracts the initial sketch into qc-space then maps from qc-space to new geometries.
