PROBLEM TO BE SOLVED: To provide a design verification system capable of displaying a three- dimensional virtual space by use of three-dimensional data generated by a CAD device and verifying a design. SOLUTION: In this design verification system, a CAD device 11 generates a design drawing including a flow line and generates the three-dimensional data. The three-dimensional data associates and records a flow line object present on the flow line and an adjacent object adjacent to the flow line object. A three-dimensional virtual space display device 13 displaying the three- dimensional virtual space decides whether the attention flow line object is present in a visual field range or not when displaying the received three-dimensional data, selects only the flow line object included in the visual field range and the adjacent object associated therewith, and constructs and displays the three- dimensional virtual space. Thereby, it is unnecessary to decide to the all the objects whether the object is present in the visual field range or not. Accordingly, the three-dimensional virtual space is effectively displayed, and the optimum design verification system can be realized. |
