The system is based on a commercial available scanning and vectorization unit. Since the vectorization results are far from being perfect, a postprocessing component to remedy some of the weak points have been created. The improved vectorization results permit a knowledge- based interpretation of the drawing content along with error detection and drawing redesign.enblackboard architectureknowledge based interpretationrecognition of graphical primitivevector data postprocessing670conference paper
