hi Jane,
Thank you for your answer.
The real problem don´t occur on a 3d surface. I dont have the tetrahedral mesh. I just have a bunch of triangles in space.
Best regards

Hello,
once you have the tetrahedral mesh generated with `CGAL::make_mesh_3()`,
you can extract the surface with
`CGAL::facets_in_complex_3_to_triangle_mesh()` [1]
Best regards,
Jane.
