hello,

i'm new on this forum and not verry good at english.

i got a problem.
i want to cleanup a mesh of a airplane, but what ever i did won't changed.

the problem is that every time i hit the clean up tool, it gives me the same faces.
by the way i just set the faces with more than 4 sides "on".

i include also a pic of the problem.

i tried all ready to export as obj. and delete history



thx
