Hello everybody,

I first want to thanks all the CGAL developers : my program which use 
CGAL 3d nef module begins to give the result I expected :-). But... I 
still have 2 questions :

1) In the binary operation between two 3d nef polyhedrons :
During execution, just at the end of the function "binary_operation" 
(Line 1245 in SNC_decorator.h)  the assertion "sim.simplify" is 
(sometime) not true and the program ends !
I would like to know if somebody already had this problem...
What mean the assertion "simplify" (I didn't find an explanation in the 
CGAL documentation) ?

2) How can I convert a Nef_Polyhedron_3 which is not simple (a face has 
a hole in it) in a Polyhedron_3 (which I visualize later in VRML format) ?
Is there already a simple procedure which do so or do I have to program 
an algorithm ( which for example triangulate the non-simple-face ) ?

Thanks in advance.
Olivier.
