The SolidWorks eDrawings Manager, located on the left side of the SolidWorks eDrawings Viewer window, displays tabs that let you manage file information.
When you open a file, the most appropriate tab opens automatically. For example, when you open an assembly file, the
Components tab

opens.
Certain functionality, such as the ability to markup and measure files, is available only if you have SolidWorks eDrawings Professional installed. See SolidWorks eDrawings Professional Overview for more information.
