A product design CAD data reconstruction unitreconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database, and the product design CAD data is corrected along a design surface of the corrected design.
