Alternatives to the View Control Bars
It may be that you want to reclaim the screen "real estate" used by the view control bars. The View Control toolbox and view control pop-up menu also provide access to view controls.
The View Control Toolbox Alternative
The same view controls that are in the view control bars also are available in the View Control toolbox.
This toolbox also contains several view controls that are enabled only while the active model is 3D.
The View Control Pop-up Menu Alternative
Using the view control pop-up menu is an easy way to select view controls.
