I'm having trouble converting Subdiv back to poly

[emosick]

Hello! Can someone please help me answer these questions:

I am trying to model a human head using subdivisions, but everytime I covert my subdivisions to polygons, I can't seem to convert my polygons back to subdivisions!!

An error message saying "Command polytosubDiv Failed. Open script editor for details." pops up.

Also, sometimes when I do end up combining the objects together, I find that I have two layers of the same objects behind each other!!

I'm really confused now lol...can someone PLEASE give me simple solution to these problems??????

Hey emosick, try opening the script editor and see what the error says. It might be complaining about non-manifold geometry.
Use the polygon cleanup tool to locate non-manifold faces and clean them up.

And also if you convert from subdi to polygon in the standard mode, you might end up with double geometry on top of each other.

(I can't remember whether it was standard mode or polygon mode in subdi that will cause trouble when converting back to poly. Try both and see which one works)

Maya have some bugs with Sub-d, and sometime when you're using undo, you can get a sub-d and polygon shape together.
for my personal workflow i use this little script

it works very nice without any bug.

Sometimes when I get a problem like that, I convert it to a nurb and then to a subdivision. seems to work for me.
