Abstract
In structural design for electronic equipments, it is difficult to check the insulation distance. Therefore, we are developing an insulation distance check technique using 3D shape data. Conventionally, structure designers visually inspected insulation distance or checked it by functions of CAD software. However, unintentional omissions and excessive detections of inspection objects were problems. In this research, we developed a distance map calculation technique and a shortest path extraction technique using voxel mesh. We compared the number of omissions and detections of this technique with the clearance check function of a CAD software. As a result, we confirmed that the number of omissions is zero and the number of excessive detections is less than that of the clearance check function of the CAD software. Accordingly, working time could be reduced by almost 60% of the conventional process.
