Hello, 

im trying to write a bit of python code which will do a check at any given time 
that all the polygon surfaces in my scene have normals pointing outwards. 

obviously with flat surfaces there is no way for python to know which direction 
is correct for the normals to be. But im talking about the concave surfaces or 
closed surfaces. I want the normals to always be facing outwards.

is there a way through python to check this automatically and reverse normals, 
without having to check each surface manually.

thanks, 
Sam
