The ViewCube is a 3D navigation tool where you can also switch between standard and isometric views.
While the ViewCube is inactive, it displays the current viewpoint of the model based on the current UCS and the North direction defined by the WCS of the model. 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.
The ViewCube is displayed in one of two states: inactive (transparent) and active (opaque).
In addition to controlling the opacity level of the ViewCube when it is inactive, you can also control its size, on-screen position, and the default ViewCube orientation. The settings used to control the appearance of the ViewCube are located in the ViewCube Settings dialog box.
The compass for the ViewCube indicates the North direction as defined in the model. The display of the compass below the ViewCube is controlled through the ViewCube Settings dialog box.
Dragging the slider to the left decreases the size of the ViewCube, while dragging the slider to the right increases the size of the ViewCube.
Dragging the slider to the left increases the transparency of the ViewCube, while dragging the slider to the right increases the opacity of the ViewCube.
