Question

Hi， 
 The clipped object Surface_6_1 has multiple primitive surfaces, but its local coordinates are defined differently: Surface_6 
 How can I solve this problem, and why does this result in a rather strange calculation

Hi xin Fang, 
 The message indicates that there may be an issue with your model's geometry. However, suggesting anything based on such limited information would require much guessing, which is not optimal. I suggest you submit a Case with a description of the issue and attach your model, and we will be happy to investigate further:
