Is it possible to use one PLY file as ground truth to classify another PLY file using the CGAL Polyhedron Demo?

[pmff96]

Sorry for bothering once more... As the title mentions, is it possible to import one PLY file, manually label it and train it using the CGAL Polyhedron Demo, then to import a different PLY file with a scene containing the same object classes as the first one and to use the training results of the first one as the ground truth of the second one (instead of manually labelling data in the second file to use as ground truth)? If so, how can one do that? Thank you for your time, and again, I apologize for the inconvenience
