I've digged into the archive and found the answer Peter Gave you:

Just use the undocumented function:

N = N.intersection(Plane_3(a,b,c,d));

If I understand correctly, it's senmatically equivalent to 

N = N * Nef_3(Plane_3(a,b,c,d), Nef_3::INCLUDED);

except the fact that with it it's not mandatory to use an extended kernel.

One more question:
Do you use the indexed items type, i.e. SNC_indexed_items, or just the 
default one?

Thanks
