I just downloaded Solidworks 2018 and I opened up a STEP file that I'm working on and noticed 2 issues.

1. "open part" option in the assembly is no longer there. I also can find the feature in the custom menu options.
2. When I go to "save all" it only saves an assembly and not the individual part files. I checked the location and its showing that the parts are in the folder, but I can not see them.
