There is a penalty to be paid for saving files automatically. If you only want modified files saved. the system has to go through memeory and 'pick out' which ones to save. Then you have the time to write the file data to disk, while you wait for NX to complete the task. Oh wait, we don't have write access to some of the modified files. Does NX save them too? Where do you save the files? If you run a PDM system on top of NX, do you save the files to your workspace or a temporary directory in the OS? How does a temporary OS directory get cleaned up so you don't have disk space being used that is wasted after you have exited NX? Does NX delete the temporary disk space when it exits?
What do you do with these temporary file saves? Use them as a recovery if NX crashes? Now the system has to figure out to load your temporary saved files and integrate them with the ones you are loading that were not modified. In a PDM system that would be very hard to do.
The save reminder tool is there to tell you that you have been working for XX minutes and you really should save. The best thing to remember when working with any CAD system is the 3F's.............File Fairly Frequently!
UG, prior to V10 which was released in 1994, had an autosave that would be triggered after a time delay and when you went to the top level menu. Many times you were doing something complicated and you had to go to the top menu for your next command and BAM you were hit with a time delay while the system did a backup of your file. I don't know many people who even turned it on.
