Hi Stefano,

very nice geometry !

Are you *sure* that each line shared by two triangles is only defined once ? (it seems to be the case...)

When you try to create the volume with the GUI and you click on a first surface, you can see that almost all the 
surfaces are then selected and change color to red. But the GUI keep asking to select volume boundary to fully close the 
volume. Due to the complexity of the geometry, it is very difficult to detect with the eye by zooming on every part of 
the geometry if some surfaces are missing, so I cannot see there is a real problem in the geometry or if some surfaces 
are left unselected...

Converting your CAD file to the STL format and then converting it to .geo is not the best solution. Do you have access 
to the original CAD file ? Can you try to export it to the STEP format instead ?

Regards,

Dave
