In NX, there is no ‘Autosave’ option or functionality available. However, there is a customer default setting available as ‘Save Changes Reminder’ which displays a reminder dialog to the user at specified intervals of time.
This customer default setting was introduced in NX 4. To find this setting, Go to
File > Utilities > Customer Defaults > Gateway > General > Part tab > Interval for Save Changes Reminder
You can set the interval between 0 to 120 minutes to display the reminder. By default it is set to 0 (zero) means that the reminder is disabled.
If you set time to 5 minutes, then a reminder will be displayed in new NX session after 5 minutes from the last save. To disable reminder, set the interval time to 0 (zero) minutes again.
