The ViewCube is a 3D navigation tool that appears when the 3D graphics system is enabled and allows you to switch between standard and isometric views.
In Object Viewers, the ViewCube is always visible. When you position the cursor over the ViewCube, it becomes active. You can switch to one of the available preset views, roll the current view, or change to the Home view of the model.
Note: When you access the ViewCube from Style Manager or from an embedded Object Viewer, no UCS option and no compass are available.
