Hi Giovanni, there are some vertices that need to be snapped on the "rectangle". Just a trick: you could extend all internal lines in order to intersect the external rectangle and then polygonize them. Sorry for my approximation, but it's a topological problem that needs further investigation and I haven't enough time to study it now.
