Hi Michael,

Thanks a lot for the patch! I've been testing this object again, and a few others that
were giving similar problems, and it seems like it fixes that problem with Join.
I've tested the same operations with and without the patch, and I can see clearly
the difference. There's no need of scaling, and no holes either.
I'll keep testing just in case I find any problem with it.


About the segments continuity thing... do you think it would help (and it would be possible)
to specify the angle of tolerance... like a way to avoid the automatic refinement and let it be
spedified by the user. Like give it a margin in that angle of tolerance to keep the same number
of segments along a curved surface.
I'm not sure how that operation works, so maybe what I'm saying doesn't make any sense :)).

In any case, I know you have other priorities and still, you'd have to thing about that to see what
the side effects would be.


Again Michael, thanks a lot!!

Jacobo.
