1. Check whether the menu bar and status bar are hidden. If so, right-click the toolbar area, select the Show/Hide Toolbar option, and make sure that the menu bar and status bar are selected.
2. Check the interface configuration file. You can try reloading the default interface configuration file of AutoCAD to restore the menu bar and status bar. The specific operation is: enter "CUILOAD" in AutoCAD, select "Default" configuration file in the pop-up "Customize User Interface" dialog box, click "Load" button, and then close the dialog box.
3. Check the installation files of AutoCAD. If the above methods fail to solve the problem, you can try to reinstall AutoCAD20 16 to ensure that the installation file is complete and undamaged.
