Thanks a million, thought I had done that right but it's a bit hard to remember the points (beeing able to attach identifiers to points would be nice - and show its 3d coordinates when hovering over it ...).
Could you possibly give me an example of the "quadrilateral" face declaration as I hear this word the first time.
CGAL doesn't seem to allow you to have negative closed spaces, and "helpfully" reverses them if it finds one. This prevents exporting objects with hollow spaces, but it should also allow you to fix a polyhedron with all of its faces in the reverse winding order (though not a mix of clockwise and counter-clockwise) by using render().
Note, I haven't tried this, and it's possible (though unlikely, because it probably would have been fixed by now if it were the case) that this check happens right before export, and wouldn't affect render().

I find a reverse function useful in cases where the natural ordering of
points is anti-clockwise.
I meant that faces don't have to be triangles so in this case they could be
