Or you can also try this: (sweep Faces with path) Sans titre.jpg behzadmaha likes this. __________________ In memory of my friend Hervé: CFD engineer & freerider

Actually, I'm not having a smooth straight pipe but it has a constriction (vena contracta). I got the 3D geometry by revolving but Gambit was not reading it as a volume. Once i convert it to volume , then i can start meshing. The thing is, how make it as volume? I look at 3D meshing tutorials, it all start with creating volume.
