Hello
I´m generating off files from an IFC file where I´m respecting the off 
form. Althought this, while reading the it to convert it to a polygone, 
it´s always an empty polygone.
This is an example of the off file
Please, do any one have an idea why I´m not getting the Polyhedron.

Thanks in advance
