The AutoCAD Civil 3D ribbon is the primary user interface for accessing commands and features.
Commands available from the ribbon are organized into tabs. Each tab is organized into a series of panels, which are labeled by task.
The ribbon is typically turned on (displayed) by default, and can be displayed or removed using the Ribbon and RibbonClose commands.
There are two basic types of ribbon tabs: static and contextual.
Static ribbon tabs are always displayed when the ribbon is turned on, and they contain most of the functionality located on the menu bar drop-down menus and toolbars. Static ribbon tabs have a gray background color.
Contextual ribbon tabs are displayed automatically when you select an object or invoke an object-specific command. For example, when you select a pipe network object, the Pipe Network contextual tab is displayed.
Contextual tabs contain commands that are related to the currently selected object. Most contextual tabs can be closed simply be deselecting the object.
Multiple Object Select Ribbon Tabs
When multiple types of objects are selected simultaneously, the Multiple contextual tab is displayed in the ribbon. For example, if you select both a pipe network object and an alignment object, the Multiple contextual tab is displayed.
