感谢各位，看到各位的回复。
的确，这样做是可行的。我在v4时期就是这样修补圆角的https://www.bilibili.com/video/BV1Zq4y197ii?p=5
我所表达意思是NSIDED产生面的效果不够好，例图：
（Thank you all for your responses.
Indeed, this is feasible. This is how I repaired the rounded corners during the v4 era ，What I mean is that the effect of the NSIDED generated surface is not good enough, as shown in the example image:）






可以看到，使用NSIDED产生曲面的部分，曲面被分成多块，并且衔接处过渡不够光顺。
至于圆角的例子是因为原本我想做球化圆角（如CATIA那样的熔接面）而恰好NSIDED对这种情况效果不佳。我知道用Network等方式能达到更理想的效果，但这与展现的效果有差距。（http://moi3d.com/forum/lmessages.php?webtag=MOI&msg=10714.1）

（As can be seen, the part of the surface generated using NSIDED is divided into multiple blocks, and the transitions at the junctions are not smooth enough.
As for the example of rounded corners, it was because I originally wanted to do spheroidized fillets (such as CATIA fusion surfaces), but NSIDED happened to have a poor effect on this situation. I know that using methods such as Network can achieve more ideal results, but there is a gap between this and the displayed effect.）
