ViewCube is used to reorient the current view of a model. You can reorient the view of a model with the ViewCube by clicking pre-defined areas to set a preset view current, click and drag to freely change the view angle of the model, and define and restore the Home view.
The ViewCube provides twenty-six defined areas you can click to change the current view of a model. The twenty-six defined areas are categorized into three groups: corner, edge, and face. Of the twenty-six defined areas, six of the areas 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 areas 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.
You can also click and drag the ViewCube to reorient the view of a model to a custom viewpoint other than one of the twenty-six predefined viewpoints that are available. As you drag, the mouse pointer changes to indicate that you are reorienting the current view of the model. 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 outline of the ViewCube helps you identify the view orientation. When a view is oriented to one of the twenty-six pre-defined ViewCube orientations, the ViewCube is outlined in a solid continuous line. When a view is not constrained to one of the twenty-six pre-defined orientations, its outline is displayed as dashed.
Pre-defined orientation left, free-form orientation right.
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.
