Workspaces control the display and order in which user interface elements are displayed.
You create and manage workspaces from the user interface of AutoCAD or with the Customize User Interface (CUI) Editor. Creating and managing workspaces from the user interface is limited; the CUI Editor gives you full control over all user interface elements in a workspace. For more information about workspace customization, see Customize Workspaces.
You can perform some basic customization of a workspace from the user interface.
The CUI Editor provides an editing environment to customization a workspace.
