PURPOSE:To improve input operabillty, to make a retrieval result easy to confirm, and to improve man-machine interface. CONSTITUTION:When drawing retrieval processing is performed by computer aided design, a computer 10 performs the registration and update of a retrieval key word data base 32 by a retrieval key word registration and update means 13 based on the output data of a retrieval data registration and update means 12. A retrieval condition is set by retrieval condition setting and selection means such as a retrieval level selection means 14, a retrieval group selection means 15, and a retrieval target drawing number selection means 16, etc., via a window menu on a display device 51, and drawing hierarchical structure and the relation of similar drawings are displayed on a display screen based on the content of the retrieval key word data base 32. Drawing structure is retrieved by a drawing structure retrieval means 17 and a retrieval result display means 18 based on the selection result of the retrieval target drawing number selection means 16 and the content of a retrieval data base 31, etc., and the retrieval result is displayed on the display device 51. |
