| Initial value: | 50 |
Valid values are from 0 to 100 percent. When set to 100, the ViewCube appears fully opaque against the drawing window and obscures all objects under it in the viewport. When set to less than 100, the ViewCube fades into the drawing window, which results in the objects under it to appear less obscured. If set to 0, the ViewCube is not displayed in the viewport unless the cursor is positioned over top of the ViewCube's location.
