Toolbar customization can be as easy as placing or resizing a toolbar in the application window to gain drawing efficiency or space. You can also create and modify toolbars and flyout toolbars, add commands and controls, and reposition and remove commands and controls from a toolbar.
Some of the simplest toolbar customizations can make your daily drawing tasks more efficient. For example, you can consolidate frequently used commands and controls onto one toolbar, remove buttons that you never use, or change some simple toolbar properties.
You can use flyouts to group related commands together on a toolbar.
Toolbar controls are drop-down lists of items that can affect the objects in a drawing or the way the program behaves from a toolbar. For example, the Layers toolbar contains controls for defining layer settings. In the Customize User Interface (CUI) Editor, you can add, remove, and relocate controls within toolbars.
