Hi Khoa,

the file seems to have several problems. One problem that
I identified is empty facets. For instance facet number 107
reference the vertices

40.470001 43.279999 0.990000
40.470001 43.279999 -0.170000
40.470001 43.279999 0.390000

All of them lie on a single line. That's problematic to
handle when you want to create a polyhedron.

I still try to figure out other problems with your file. I have some
small program that helps handling such problems, but it can't cope with
your file. So i am upgrading it at the moment.

Peter
