View rotation

Arrow keys Specifies the angle increment for view rotation when you use the arrow keys to rotate the model.
Mouse speed Specifies the speed of rotation when you use the mouse to rotate the model or assembly component. To get finer control and slower rotation, move the slider to the left.

Transitions

Enables animation-like changes to the display of part and assembly documents when you change from one display state to another. You can independently control the following transitions:
View transition Controls the animation when changing from one view orientation to another. For example, from a front view to an isometric view.
Hide/show component In assemblies, controls the animation when you turn the visibility of selected components off or on.
Isolate In assemblies and multi-body parts, controls the animation when you isolate selected components.
View selector Controls the animation when you activate the View Selector.
Move the slider to adjust the animation speed or to Off to turn off a specific view transition. When a transition type is turned off, the model jumps immediately to the new display state.
To optimize view display performance, larger models might not show the animation.
