I built up a a pretty simple character in polygons. I just started off with a half a box and mirroed the other half. THen I jsut did the normal extrusions and split polys. I combined the two halves when I was done.

I wanted to convert it into subdivs, but I got this error:

deleteInternalValence2Verts |polySurface1|polySurfaceShape1;
polyToSubdiv -ap 0 -ch off -aut on -maxPolyCount 1000 -maxEdgesPerVert 32 |polySurface1|polySurfaceShape1;
// 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. //

So I went ahead and did the cleanup, with the nonmanifold option checked. I'm not sure exactly what it means, but I tested it anyways. The conversion to subdivs then worked, but hole appeared in my model. Can anyone help me out on this?

The hole's in the subdiv appear only when there are hole's in the poly moddel.
In the Polygon Cleanup Options dialog, there are some other options that might come in handy:
- Construction History
- Faces with Holes
- and as you mentioned already, Nonmanifold geometry

if that doesn't work select (drag marque, not click or you might select only one vertice while there are in fact 2 verry close to each other) all you vertices that might cause the problems and weld them (use a verry low distance value, to prevent welding of desired geometry)
What I discribed can also be done on the subdiv model in polygon mode (right mouse button click on your subdiv mode > polygon)

Hope this works for you
