Hello,

I am trying to load a 3D mesh from an OFF file using
CGAL::scan_OFF(). The mesh has been generated by some
simplification software.

I get the following error:

CGAL::Polyhedron_incremental_builder_3<HDS>::
lookup_halfedge(): input error: facet 302 shares a
halfedge from vertex 214 to vertex 213 with facet 300.

I don't quite understand why two facets sharing a
halfedge is a bad thing.

I presume that CGAL is enforcing some restriction to
ensure correct geometrical processing. In that case,
is there any software that will load in my "broken"
mesh and fix it for me ?

thanks in advance,

Lyndon Hill
