This paper discusses the design of intelligent sketch editing tools exploiting intermediate levels of visual interpretation known as {\it Perceptual Organization}. Sketches are much more than an accumulation of strokes: they convey information largely through spatial configurations and patterns {\it among} markings. We propose that the detection of this visual structure, based on the principles of Perceptual Organization, will make sketch editing tools more useful for a wide variety of hand-drawn and formatted diagrammatic material. We review our efforts which are embodied in a perceptually supported sketch editing tool, called ScanScribe.
