Could someone please explain the reason for saving intermittently when it does nothing. Just lost two days of work, saved many times about every 20 min. I just opened a drawing to print and SW crashes, no big deal i didn't edit anything in that drawing. When i reopened the stuff i was working on and had saved many many times, all changes were gone as well as all parts i had made. So why does SolidWorks have a save button if it does nothing until you click the X and successfully close your part or assembly.
This didn't happen in SW2014
