We'll close out the year with a tip for closing multiple drawings using only one command.
Go to the Display tab of the Ribbon and in the User Interface panel expand the Close cascade button.
The Close cascade in the Ribbon.
The first button will close the current drawing and you will need to save any changes, if you haven't done so.
The second button will close all of your open drawings and issue a Save automatically for you.
The third button will close all your open drawings, but pause on any that have not been saved.
