Abstract
A figure management system in which plural kinds of figures concerning the same part to be managed are modified. The figure management system includes a figure DB for storing data of figures including topological figures, an attribute DB for storing object attribute data, input and output devices, and a computer for managing figure and object attribute data. An ID code common to features indicating the same object is assigned. On input of a new figure, feature-attribute matching is performed between a feature having no ID code on the new figure and existent object attribute data. If any inconsistency is found the feature is indicated as a discrepant feature or a renewed feature.
