I have some questions, where is the error?  
Question 1:For example, a standard square, as seen in the red line labeled position on the image, is not at a 45 degree diagonal angle after linking the diagonals?

Question 2: On this part, the selection surface indicates that the object is 10mm thick, but the selection side becomes 7mm?

Are these bugs? I’m a little concerned about accuracy.

我有些疑问，是那里出现了错误？  
问题1:例如图像上红线标注位置看到的，一个标准的正方形，链接对角线后，对角线角度不是45度？

问题2：这个零件上，选取面表示该物件为10mm厚度，但选择边就变成了7mm？该物件被我复制并移动到旁边检查，复制物件就是正常显示都为10mm。

这些是BUG吗？我对精确度感到有些担忧。

感谢 Roxy回应。  
我的ipadpro是2015年的12寸版本A1584，系统版本14.7.1（好像发现问题后，apple更新了一次iOS版本，所以这个bug应该是在前一个IOS版本）  
如果这几天没有自动更新的话，shapr3D版本是4.9.1（1601）#224bd283  
因为已经过去了几天，这些发现问题的实体估计已经被我删除或更换了。我尝试复原这个问题，但可惜这个bug似乎无法复现。如果后续还有此类问题，我再尝试保留下来。  
另外，我保存不了.shapr格式，因为没有订阅。 😑实在太贵了！

for support team:  
iPad pro 2015 12’ A1584, iOS 14.7.1 (But after he found the problem, Apple updated iOS, so the bug should be in the previous iOS version.)  
Shapr v4.9.1（1601）#224bd283  
Cuz it’s been a few days, the problematic WS was deleted already, and he couldn’t reproduce the problem again now. Also he can’t save to .shapr cuz he’s a free user.
