Save History Information of Model Objects

You can save information about modeling events throughout the history of a model. You can use this information to gather information about the model, such as when the model was created, and when specific objects were changed. Use the features in the History Options tab of the Model Editor to set options for how historical information is tracked. You can view history events on the Notes tab of an object for which you are tracking history.
