I used Bfuse to fuse two shapes. Two warnings are generated, and the fused Shape is incorrect. Is this a bug? Is there any way to avoid it?
Repetition steps:
restore topUnionShell.brep a
restore topUnionBoss.brep b
bfuse c a b
Warning: Some of the edges passed to the Face Builder algorithm have not been classified and not used for faces creation

There is some tangent problem in this case. Using fuzzy value can help. I experimentally deduced that for this case the fuzzy value from 1e-4 to 1e-3 helps to produce the expected result.
However, you are welcome to register a bug for making bfuse produce correct result without using fuzzy value.

Thanks!
Although the warning message is still there, the fused Shape looks normal.
I see that someone has submitted the same Bug, can I add it directly below?

I think it is hardly the same, because shapes are different. The presence of the same messages does not mean the same cause of the bug.
