By default, the Building, Interiors, Landscape and Terrain toolbars are displayed in tabs below the menu bar. You can change any tabbed toolbar to be displayed as a non-tabbed, free-standing toolbar.
To display toolbars in non-tabbed format:
Select Settings > Toolbars.
Make sure the check box of the toolbar you want to display is enabled.
Disable the toolbar’s Tabbed check box.
Click OK.
