Hi Pilou, your example #3 was a bit easier to examine since there are not quite so many pieces.

But this is also another case that will be difficult to fix up soon. It is a bug in the processing of 2 surfaces that touch each other like this:



In some circumstances like this where 2 surfaces just exactly touch each other at a point, the geometry library gets confused about which resulting piece is supposed to be kept and which is supposed to be discarded. I've seen this one a couple of times. It's another one that I hope will be solved by an update to the geometry library in a future version after V1.

It's another example of problems involving different pieces just barely overlapping or touching each other.

yes it's odd bug :)
But seems there is in general another solution for have the same result by a another way :)

Yes, this is a limitation of the current fillet engine. Fillets won't cross an edge boundary like this. I hope that this will be improved in future versions of the geometry library that I am using

Does any chance you find new fillet library for the V1?

Not the complete new library, but there is still something left for me to try. There is a different interface to the same library that seems like it tries a couple of different approaches if there has been a problem with the standard method.

It is possible this may help out a bit on some thing that cause problems, but I'm not quite sure how much of a difference it will make yet.
