Abstract
In the structural design for electronic equipments, it is difficult to check the insulation distance. Therefore, we are developing an insulation distance check technique for large-scale CAD data. Conventionally, we developed a distance map calculation technique and a shortest path extraction technique using voxel mesh. However, the calculation is too time-consuming for CAD data with thousands of parts. In this research, we have developed an appropriate mesh region technique and a parallel processing technique. We confirmed that clearance and creepage distance using this technique was within 1% error based on the clearance check function of a CAD software. We compared the working time of this technique with the conventional method. As a result, we confirmed that the working time was almost 5% of the conventional process.
