Syntax
UCLASS&40;&41;
class UDragAlignmentInteraction :
public UObject,
public FDragAlignmentBase,
public IModifierToggleBehaviorTarget

Interaction that can be added to (potentially multiple) UCombinedTransformGizmo object to allow them to snap to scene geometry in rotation and translation. Generally driven by an externally-provided UKeyAsModifierInputBehavior, or alternately can be directly updated by calling ::OnUpdateModifierState()
