I can operate using toolbars and typed commands, but would like to do more experimentation with the RIBBON.
So...how can I restore it?
If you are referring to the "Command Manager"
2016 SOLIDWORKS Help - CommandManager
e.g. right click the gray area in the top and select it.
you can use the Tools menu > Customize...
this may be of little help right now. Bit, if you capture your settings with the copy setting wizard. It's very easy to restore them. You may wish to do a back-up when you have everything the way you like it.
