The subject invention provides a system and/or method that facilitates synchronizing a diagram file with a code allowing a data representation application (e.g., class modeling tool) to accurately display at least a type, a member and relationships therewith. An association component can associate an orphaned shape from the diagram file to a type within an edited code wherein such edit entails a renaming of a type. The association component can utilize a heuristic search in order to associate an orphaned shape with a type. Moreover, the association component can utilize a distance metric and/or match confidence in order to indicate and associate a plurality of orphaned shapes to a plurality of types with a high probability.
