Hi moebious0815,

Thanks for the reply. So, in short, even with 68 bad polygons, you want the algorithm sort it out for you and provide a perfectly solved Boolean operation.

Even some models are based on flat polygons, for example, not even producing a volume" (when you “explode” the collection, you see how unusable it is constructed).

I get your expectation, all of that care to create clean models is not needed; it should work no matter what anyway. Sorry, there's nothing I can help you with.

In short, you state that it is not working, which means you need to contact the Tech Support.
