Thanks ABX,

I am working with a closed mesh() and wanted to see if there were holes in it
(I think there are) and used 'interior_texture'. It gave many triangles with the
'interior_texture'. If I altered the sequence of the vertices of some triangles,
it didn't matter much. Some did change, but other didn't.
I did remember something about 'clock wise' or 'counter clock wise' but
my example file told me something different. That's why I asked.
I will try the 'inside_vector' and see if it helps.

Thanks any way.
