I'm contacting you to find out if there is an easy way to take notes in an assembly file in Solidworks.
I have a lot of notes to take and add to my assembly, it would be an advantage to save them directly in the 3D file, in order to consult and save them easily.
If the "Design Workbook" folder does not appear in the FeatureManager, you can enable it in SW's general options so that it is shown by default. If you save your template, every time you open a new document, you'll have access to the content.
