I downloaded and installed Ultimaker Cura 3.5.1 however, I have no "Save As" option in the menu! There is only "Save", which wants to save to .3MF file. I tried uninstalling and reinstalling but no luck. Does anyone have any suggestions? I'm back to 3.4.1 and it's working fine. I think I'll stay with it until all the bugs are worked out of the new version. With that said, I can't believe that Ultimaker makes this software available to us free. I appreciate all the hard word work that goes into making this software. Thank you Ultimaker!
