AutoCAD 2014 offers file tabs as a fast and visual way to switch between open drawings or to create new ones. You can turn the file tabs bar on or off using the File Tabs control on the View ribbon tab. When file tabs are turned on, a tab for each open drawing is displayed at the top of the drawing area.
File tabs are displayed in the order they were opened. You can drag tabs to change their order. If there is not enough room for all the file tabs to display across the AutoCAD window, an overflow menu at the right end of the file tabs bar provides access to the additional files.
A lock icon on a tab indicates that the file is open as read-only and an asterisk indicates if the file has been modified since its last save. When you pass the cursor over a file tab, preview images of the model and layouts are displayed. If you pass the cursor over one of the preview images, the corresponding model or layout is temporarily displayed in the drawing area and Plot and Publish tools are accessible from the preview image.
The right-click menu for file tabs enables you to create, open, save, and close files, including the ability to close all open files except the one on which you right-clicked. You can also copy the full file path to the clipboard or open the file location in Explorer.
A Plus (+) icon to the right of the drawing tabs enables you to easily create new drawings, automatically adding their tabs as they’re created.
