The Application menu is accessible from all workspaces. The AutoCAD Application menu has the following commands on the Application menu:

 New: Create a new drawing or a new sheet set. I discuss sheet sets in Chapter 25.

 Open: Open an existing drawing or sheet set.

 Save: Save the current drawing in the current location. If the current drawing hasn’t been saved, you’re prompted for a filename and a location.

 Save As: Save the current drawing with a new filename or in a different location or in another format, and make the newly named or located file the current drawing.

 Import: Open drawing files stored in formats other than DWG. I discuss this feature in Chapter 24.

 Export: Save the current drawing to one of a large variety of file formats, including Design Web Format (DWF), PDF, and several other CAD file formats.

 Publish: Send a 3D model to an outside 3D printing service, or create an archived sheet set. (AutoCAD LT doesn’t support 3D.) Use eTransmit to create a package that includes all files referenced by the selected drawings, or share the current drawing by using your configured email client or Autodesk’s Share service.

 Print: Print a single drawing or batch-plot multiple drawings, create or modify named page setups, and manage plotters and plot styles. I cover most of these operations in Chapter 16.

 Drawing Utilities: Set file properties or drawing units; compare the differences between two drawings; purge unused blocks, layers, and styles from the current drawing; and audit or recover damaged drawings.

 Close: Close the current drawing or close all drawings. If any drawings have changed, you’re prompted to save them before AutoCAD closes the file.

The CLOSEALLOTHER command closes all open drawings except for the active one. (Unfortunately, the command doesn’t appear on the Ribbon menu, so you have to type it at the command prompt.) You'll appreciate the significance of this feature after you open 20 or so drawings looking for a particular one and now want to close the rest.

In addition to the Application menu’s file menu items, it has a few other features worth a mention:

 Recent Documents: When you choose this option, the right pane displays a list of recently edited drawings that aren’t open. You can show them in a simple list or as thumbnail images. You can also pin them to stop them from scrolling off the list. Naturally enough, clicking a filename opens the drawing. The Recent Documents feature is hardly necessary, however. Instead, click the Start tab near the upper-left corner of the screen to bring back the Start screen, which displays a scrollable series of thumbnail views of the last few open drawings, as shown in Figure 2-1 earlier in the chapter.

 Open Documents: Choose this option to see which documents are already open, and click an item to switch to it. This feature, like Recent Documents, isn't necessary because a series of tabs appears across the top of the graphic screen, one for each open drawing. Hovering the cursor over a tab produces a quick preview of its drawing, which makes jumping from drawing to drawing much easier compared to earlier releases.

 Options: Click this button to open the Options dialog box, where you can adjust hundreds of system settings. You can also open Options by typing OP (the alias for the OPtions command).

 Search: When you’re unsure of a command name or you want help on a topic, just start typing in the Search bar, at the top of the Application menu. AutoCAD quickly displays a categorized list, complete with links to start commands or to access the online Help system. See Figure 2-4.You can also search directly from the command line. Just start typing the name of a command. As you type, AutoCAD displays a list of what it thinks you are searching for. When you see the one you want, click the question mark beside its name to get help about the selected item.

A quick way to close AutoCAD is to double-click the red A. AutoCAD asks whether you want to save unsaved drawings before it shuts down.
