Can't convert Poly to Subdiv
Hi y'all !

can you please help me with te rooftop of my car... It seems impossible to convert it to subdiv it's driving me crazy.. the other parts of the seem to have no problems with that except the roof...Maya keeps telling me this :
/ 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. //

But whatever I do, everytime maya comes with this message! I cleaned it up for a thousend times but doesnt work!

Can somebody please help me?

a desperate fool

When you alter the cleanup options, are you ticking the box next to nonmanifold? You should, then clean up the roof and it should convert fine.

the problem you have with the mesh is that you have faces i have selected in the screenshot.. have a gander at the maya docs, do a search for nonmanifold , im not sure how to explain it so the docs should do a better job than i can

yeah that tends to happen to me if I leave "keep faces together" on when extruding. If i find that I've done this I normally jsut start again cause it's not really tat easy to fix it.


I meant to say: if I leave "keep faces together" off
