buttons that operate independently of standard
snaps.
Angle (deg)—A global setting, in degrees, that
determines the angle of rotation for a n umber of
features in the program, including the standard
Rotate transform. As you rotate an object (or
group of objects), the object moves around a given
axis in the increment you set. Angle snap also
affects the following:
• Pan/Orbit camera controls
• FOV and Roll camera settings
• Hotspot and Falloff light angles

Percent—Sets a percentage increment during a

The effect of rotating and scaling with snaps
depends on whether

or off:
•WithAutoKey

, snap toggles are disabled,
while Angle and Percent snaps remain active.
Rotation and scaling occur around the pivot
point of the object.
•WithAutoKey

,rotationsandscalesoccur
around the snap point. For example, using
