Hi it's me again with another problem i'm sure you can help me with. I just made my poly dog and now i wanted to covert it into a subdivision but i always get an error.

[B]polyToSubdiv -ap 0 -ch 0 -aut off -maxPolyCount 1000 -maxEdgesPerVert 32 |polySurface8|polySurfaceShape11;
// 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 Polygons->Cleanup with the nonmanifold option. //
// Error: Command polyToSubdiv failed. Open Script Editor for details. //
B]

someone knows what that should mean i already tired the clean up thing with the option: "Edges with zero lengh". I don't really know what's meand with "nonmanifold option" i come form austria and so my english isn't so good but I also didn't find a translation on the internet.
pls someone help me.

what i forget to ask is: in the video tut he cleaqns everything up with merge vertices but that doesn't do anything so i just did everthing with merge to center. where could the problem with the vertices tool be?
