Abstract

A system which includes a CAD system and an electronic filing system, wherein when vector data such as figures and their names are converted to image data for storage, the system automatically extracts, from the vector data coming from the CAD system, data that correspond to predetermined character attributes, maximum numeric attributes, primitives of each figure and the topology thereof. The extracted data is set as key-words and made to correspond to the image data for registration and storage in the electronic filing system. In searching for desired image data, key-words corresponding to the desired image data is input for retrieval and output of the desired image data.
