Viewport types (also known as title marks) define settings for viewports.
These settings control display attributes of the view title (for example, whether the view title and its horizontal line display on a sheet). You can apply viewport types to views on a sheet.
Note: To change the information included in a view title or its display attributes, create or edit a view title type.
