Hello,
I'm looking to do a Booleene union operation to have a signe volume instead three part, but GMSH show me an error.
You will find attached CAD .stp file and GMSH .GEO file.
Think you in advance for your feedback,
Best regards,
Soliman
------------------------------------Bonjour,
Je cherche à faire une operation booleene Union pour avoir un seul volume au lieu de trois parties, mais lors du maillage 3D GMSH m'affiche une erreur.
Ci joint le fichier CAO .stp et le fichier .GEO en question.
Cordialement,
