Poly to Subdiv
 

Hi all,
I have a small problem with converting Polygons to Subdiv. I'm learning in maya and I stucked. I don't know how to continue. After trying to convert to Subdiv I've get an this error:
-------------------------------------------------------------
deleteInternalValence2Verts |polySurface8|polySurfaceShape9;
polyToSubdiv -ap 0 -ch off -aut on -maxPolyCount 1000 -maxEdgesPerVert 32 |polySurface8|polySurfaceShape9;
// Warning: Nothing is selected. Select objects or components to delete. //
// Error: polyToSubdiv1 (Poly To Subdiv Node): One or more vertices is nonmanifold.
// Nonmanifold geometry cannot be converted to a subdivision surface.
// To clean up nonmanifold vertices, use Polygons->Cleanup with the nonmanifold option. //
// Error: Command polyToSubdiv failed. Open Script Editor for details. //
-------------------------------------------------------------
Please can somebody explaine me, how to convert poly to subdiv step by step
My project is attached

THANKS Dave

The message is directing you to do the above steps. Run the cleanup as directed to identify/correct the nonmanifold geometry. Once correct run the conversion again.

The problem is that nonmanifold geometry can give u a big headache when convertin' to Subdiv. It make ur model looks...strange and weird...
