It is proposed to incorporate 1DCAE into a virtual engineering system in mechanical system design. In order to continue using an established virtual engineering system for a long time, it is necessary to modify it in line with the evolution of CAD, CAE, analysis, and evaluation technologies. If information in CAD or the like is coded directly in the system, it will be necessary to make changes to the system. Meanwhile, if the evaluation method, etc. is changed, the user interface of the system may need to be changed. These changes require software engineers and are costly and time-consuming.
In this paper, we propose that the elements in the system be independent, that the relationship between each element be defined by JSM, and that 3D-CAD be used for user interfaces. This will allow even those without software language skills to update the technology and create a long-lasting virtual engineering environment.
