About Closing a Design Exploration Session
When you decide to close the Design Exploration session, you can choose one of the following options:
Accept your session. All changes made are accepted and applied to the models present in the Creo Parametric session. You are prompted to save your session. When you do not save your session, all information contained in the checkpoints that are not in the current state is removed from memory.
Cancel your session. You are prompted to save the session before canceling. When you do not save the session, all changes you made to the original models are discarded.
