The ViewCube provides twenty-six defined parts to click and change the current view
of a model. The twenty-six defined parts are categorized into three groups: corner,
edge, and face. Of the twenty-six defined parts, six of the parts represent standard
orthogonal views of a model: top, bottom, front, back, left, and right. Orthogonal
views are set by clicking one of the faces on the ViewCube.

You use the other twenty defined parts to access angled views of a model. Clicking
one of the corners on the ViewCube reorients the current view of the model to a three-quarter
view, based on a viewpoint defined by three sides of the model. Clicking one of the
edges reorients the view of the model to a half view based on two sides of the model.

The outline of the ViewCube helps you identify the form of orientation it is in: standard
or fixed. When the ViewCube is in standard orientation, not orientated to one of the
twenty-six predefined parts, its outline is displayed as dashed. The ViewCube is outlined
in a solid continuous line when it is constrained to one of the predefined views.

Drag or Click the ViewCube

You can also click and drag the ViewCube to reorient the view of a model to a custom
view other than one of the twenty-six predefined parts. If you drag the ViewCube close
to one of the preset orientations and it is set to snap to the closest view, the ViewCube
rotates to the closest preset orientation.

The ViewCube reorients the view around the selection set pivot point.

• When no object is selected, the pivot point is at the center of the view.
• When one object is selected, the pivot point is at the center of the selected object.
• When multiple objects are selected, the pivot point is at the center of the extents
  of the selected objects.

Roll a Face View

When you view a model from one of the face views, two roll arrow buttons are displayed
near the ViewCube. Use the roll arrows to rotate the current view 90 degrees clockwise
or counterclockwise around the center of the view.

Switch to an Adjacent Face

When the ViewCube is active while viewing a model from one of the face views, four
orthogonal triangles are displayed near the ViewCube. You use these triangles to switch
to one of the adjacent face views.
