[Step Sc5] The operation of the input device 3a instructs the execution of the arrangement of the three-dimensional image of the arrangement component X.

[Step Sc6] Based on the three-dimensional image data generated in step Sc4, the placed component X is placed and displayed at the placement position designated in step Sc6.

[Step Sc7] It is determined whether or not the end of the component arrangement has been instructed by operating the input device 3a. If this determination is “YES”, the processing in the three-dimensional design support device 3 is terminated, and if this determination is “NO”,
The processing after step Sc1 is repeated.

In step Sc1, the placement position of the next component to be placed is designated. On the other hand, when a control signal related to the component is transmitted from the two-dimensional design support device 1 to the database 2, the control signal is transmitted from the database 2 by the control signal. The shape information relating to the part is input to the three-dimensional design support device 3, and the arrangement and execution of the three-dimensional image of the part is performed as described above.
