OK，先看看这个(Let's take a look at this first)


仅在v5中出现。stp显示BUG，对比不连接面的情况影响似乎更严重一些。（Only appears in V5. STP shows a bug, and compared to the situation where there is no connection, the impact seems to be more severe.）


在V4以及Plasticity中显示均正确。（It is displayed correctly in both V4 and Plasticity.）

其余模型在交流群中出现时，我将发邮件给您。（I will email you once the remaining models are present in the communication group.）

Hi SUIYAN, that's a much different bug than the other one, they are not related.

This one is from the STEP importer having some difficulty with splitting edges that cross over the "seam" of a closed surface.

It's not just a display mesh problem like the other one.

You can still send them to me, at some point I will probably try to write a new split at seams function and it is good to have more test cases.
