Hi, every one, I'm trying to use CGAL to simplify a mesh which is already simple, but has some unnecessary edges. The mesh is a model created by 3d MAX of a building. The walls hav sometimes many triangles in it which adds many unnecessary edges... My goal is to remove this triangles.. a simple test is to check if adjacent triangle has very near normals, but I dont want to do this by my self, im trying to use cgal to do something like this. I have taken all triangles from the model and I've added it to a Polyhedron just like in the examples provided in the official website (Polyhedron P; 
P.make_triangle( P1, P2, P3) .... for each triangle)...

The result is that no edges were removed... so I don't know what do i need to do.. My polycies are :
SMS::Edge_length_cost   and SMS::Midpoint_placement using the ratio stop criteria... Shouldn't the walls composed by many triangles be simplified?

Any helpp or guess?

thanks!
