Hi David, so do you need any more help with this, or do you have a solution now?

But it looks like the damaged areas could be due to a bug in trimming or filleting or something like that. It could be related to the small size of that area in relation to the full surface.

It may be something I can fix by automatically tightening a calculation tolerance. If you are able to show me the steps that were done to create those areas, like if you have the model before doing it that you can send to me so I can repeat it over here, then that may help me to track down and solve the problem.
