Abstract: A method, apparatus, system, and computer program product for generating information for modifying a model. Training data comprising entities, operations for the entities, and a number of mesh quality metrics for meshes generated from modified entities resulting from the operations being performed on the entities are selected by a computer system. A set of machine learning models is trained by the computer system using the training data. The set of machine learning models trained with the training data identifies a number of mesh quality metrics for a set of input entities in a model input into the set of machine learning models.
