We have added an alternate viewing mode, Azimuth/Twist, available when holding the Alt and Shift keys. This mode allows for a different style navigation in a perspective view.
The Azimuth/Twist mode provides a "model-centric" view manipulation. The mode is similar to manipulating a model in your hand. For example, when using the right mouse button, a horizontal movement in the upper half of the screen to the right will twist the screen to the right.Imagine twisting the model by moving the cursor in the direction you want the twist to go.
When Alt + Shift are held, the mouse buttons now work as follows:
Moving the mouse horizontally controls the azimuth. Moving the mouse vertically controls the elevation.
Tracks horizontally and vertically.
Moving the mouse vertically dollies in and out. Moving the mouse horizontally twists.
The Tumble/Zoom setting corresponds to the regular AliasStudio viewing behavior.
In addition, when using the Azimuth/Twist mode, the View Step Angle option (also in General Preferences) lets you use the arrow keys to change the azimuth (left/right arrows) or elevation (up/down arrows) by the specified angle increment.
