Modifier Stack

Gizmo sub-object: You can transform and animate the gizmo like any other object at this sub-object level, altering the effect of the Bend modifier. Translating the gizmo translates its center an equal distance. Rotating and scaling the gizmo takes place with respect to its center.
Center sub-object: You can translate and animate the center at this sub-object level, altering the Bend gizmo's shape, and thus the shape of the bent object.

Angle: Sets the angle to bend from the vertical plane. Range=–999,999.0 to 999,999.0.
Direction: Sets the direction of the bend relative to the horizontal plane. Range=–999,999.0 to 999,999.0.
X/Y/Z: Specifies the axis to be bent. Note that this axis is local to the Bend gizmo and not related to the selected entity. Default=Z.
Limit Effect: Applies limit constraints to the bend effect. Default=off.
Upper Limit: Sets the upper boundary in world units from the bend center point beyond which the bend no longer affects geometry. Default=0. Range=0 to 999,999.0.
Lower Limit: Sets the lower boundary in world units from the bend center point beyond which the bend no longer affects geometry. Default=0. Range=–999,999.0 to 0.
