The converson into subdi failed and this is what I found ine the script editor :
Error: polyToSubdiv1 (Poly To Subdiv Node): One or more edges is nonmanifold.
// Nonmanifold geometry cannot be converted to a subdivision surface.
// To clean up nonmanifold edges, use Mesh->Cleanup with the nonmanifold option. //
// Error: Command polyToSubdiv failed. Open Script Editor for details. //
// Result: doSubdivCreate( "2", { "1","1","4000","32"} ) //
