Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Non-Manifold Edge

I want to convert a poly to subdivision but this errors pups up,

// Warning: Nothing is selected. Select objects or components to delete. //
// 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. //

I remodel my Object but this comes again

Is that my mistake or my MAYA'S ?

Could be the way you are modelling, the error message is telling you how to fix it"To clean up nonmanifold edges, use Mesh->Cleanup with the nonmanifold option".......dave

You have some kind of non-manifold geometry (geometry that cannot be unfolded). There are three kinds of non-manifold geo - three or more faces sharing a single edge, two or more faces connected by a single vertex, two faces sharing a single edge, each with opposite facing normals.

To clean them use mesh>cleanup with the non-manifold geometry box checked as Dave suggested.
