Abstract
Generation of a search key shape for identifying a dedicated shape with respect to three-dimensional CAD data is facilitated. A shape group registration unit registers multiple pieces of three-dimensional CAD data; a feature amount computation unit computes a feature amount with respect to each of the registered pieces of three-dimensional CAD data; a clustering unit clusters the pieces of three-dimensional CAD data based on a feature amount; a cluster center computation unit determines a feature amount of a cluster center of each cluster from a feature amount of three-dimensional CAD data; and a search key shape registration unit registers feature amount data of a cluster center as feature amount data of a search key shape.
