In Creo Parametric 4.0 and earlier the Element Definition dialog box contains all settings and references in one area and it does not include a preview. In Creo Parametric 5.0.0.0 to improve clarity and efficiency, the Element Definition dialog box is separated into two tabs, References and Settings. From this dialog box, you can also preview the proposed changes to the connector element and assess the impact before making the change. This helps to identify potential problems and simplifies the workflow.
