Hello,

Thank you very much benfarmer, just using a solid instead of a single line cutter was the solution :-)

@Pilou : thanks for your participation but as you can understand in the precedent discussions with Michael, the best way to cut while closing surfaces still use boolean cut, this avoid many time waste in re-constructing and/or closing the surfaces... When we can do it !

Cordially,
Guy
