The present invention provides a three-dimensional CAD system device with which it is possible, as necessary during design work using three-dimensional CAD, to register and refer to knowledge information which corresponds to a three-dimensional CAD model which is a subject of the work. A three-dimensional CAD system device according to the present invention comprises a storage device (1000) which stores three-dimensional CAD data (102), and a computation processing device (105) which executes design work on the basis of the three-dimensional CAD data. The three-dimensional CAD data includes knowledge-association data (104) which associates knowledge data (103) with a three-dimensional CAD object. During the design work, the computation processing device stores the knowledge-association data in the three-dimensional CAD data, and, on the basis of the knowledge-association data which is stored in the three-dimensional CAD data, queries the knowledge data which is associated with the three-dimensional CAD object. |
