It is ok now, i modeld the legs again, but now i have a problem with converting polygons to subdivisions, here is the text from the script editor: "polyToSubdiv -ap 0 -ch 0 -aut off -maxPolyCount 1000 -maxEdgesPerVert 32 |polySurface12|polySurfaceShape14; // 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 Polygons->Cleanup with the nonmanifold option. // // Error: Command polyToSubdiv failed. Open Script Editor for details. // " my model is perfectly cleaned up ! i dont know what this word means "nonmanifold"
