Transformation Limit Node
The Transformation Limit node can be used as an intermediary between two nodes to limit the effect of the parent peg's transformations onto the child, by applying a ration to the transformations applied to the parent before applying them to the child. This ratio can be set for each coordinate in the node's properties and can be animated.
Connection
The Transformation Limit node must be connected to its parent peg by its right input port, and must be connected to the peg or element it will apply the transformation to via its output port. Transformations applied by the parent peg will be recalculated by the Transformation Limit node, then applied on its child.
The transformations that are processed by the Transform Limit node are not the ones of its immediate parent, but rather, the ones of the entire hierarchy of parents it is connected to combined. If you need the TransformationLimit node to only process the transformations of one or some of its parents and ignore the parents past a certain point in the hierarchy, simply connect the first parent the TransformationLimit node should ignore to its middle input port.
The effect of the Transformation Limit node on the transformation can be tempered by lowering its Active parameter. The Transformation Limit node can also be connected to a Constraint Switch node, the Active parameter of which will be multiplied with the Active parameter of the Transformation limit node, and hence can also be used to temper its effect on its child.
Controls
Because the Transformation Limit node can significantly influence the position of its child element relative to its peg pivot, the Transformation Limit has its own pivot point. The position of this pivot can be set in its layer properties, but can also be set visually by displaying its control in the Camera view and dragging it to the desired position using the Transform tool.
Properties
Parameter  Description 
Active 
The percentage of influence the Transformation Limit node has on the transformation before it applies it to the child. For example, if its Translate X parameter is set to 50, and its Active parameter is set to 50, the effective Translate X limit will be 75. 
Switch Effects 
Defines which coordinate limits the Active parameter affects. If set to Active value, it will affect the limits for all coordinates. If set to XYZ Translation, Scale, Rotation, Scale/Skew or Skew, it will affect the limit on the corresponding coordinates. If the TransformationLimit node is connected to a Constraint Switch, this parameter will also dictate the effect of the switch. 
Translate X  The percentage of the parent's horizontal translation to apply to the child. 
Translate Y  The percentage of the parent's vertical translation to apply to the child. 
Translate Z  The percentage of the parent's translation on the Z axis to apply to the child. 
Rotate  The percentage of the parent's rotation to apply to the child. 
Skew  The percentage of the parent's skew to apply to the child. 
Scale X  The percentage of the parent's horizontal scale to apply to the child. 
Scale Y  The percentage of the parent's vertical scale to apply to the child. 
Allow Flipping  If disabled, the child element will not be flipped when one of the parent's scale transformations is negative. 
Uniform Scale  Averages the horizontal and vertical scale factors to preserve the proportions of the child. 
Ignore Parents 
If this property is set to any value but 0, the Transformation Limit node will go up its own hierarchy up to the value of this property, and consider the node at this level to be the "Ignored parent". The transformations applied by this parent and all its parents will not be affected by the Transform Limit. NOTEThis has the same effect as connecting one of the node's parents to its middle port.

Parent’s Name 
If the Ignore Parents property is set to any value but 0, this property will also be used in determining which parent to consider as the "Ignored parent". When looking up the parent hierarchy of the Transformation Limit node, if it finds any node with a matching name, it will consider it the "Ignored parent", and the transformations applied by this parent and all its parents will not be taken in account for the spring effect. NOTEWhen both the Ignore Parents and the Parent's Name parameters are set, the "Ignored parent" will be the first node in the node's parent hierarchy that either matches the name of the Parent's Name parameter or the parent level in the Ignore Parents parameter.
TIPThis parameter only works if the Ignore Parents parameter is set to any value but 0. If you want the ignored parent to only be matched by its name and not its level in the hierarchy, you can set the Ignore Parents parameter to an improbably high number (ie: 100 or 1000), and set the Parent's Name to the name of the parent to ignore.

Flatten Type 
Affects how the translations are applied in the 3D space.

Skew Type 
Affects how Skew of the parent is applied to the child.

Control Position 
The following parameters affect the pivot point used to apply the transformations calculated by the Transformation Limit node. 2D Path: The horizontal and vertical position of the pivot point are stored in a single function of control points. This makes the trajectory curvilinear and the pace of the movement set to a velocity function. Separate: The horizontal and vertical position of the pivot point are stored in separate functions of coordinates. This makes a trajectory where each point is joined by a straight line and each coordinate can have its own curve. 
Path: If the 2D Path option is selected, this allows you to create or link to a 2D Path function. (x) Axis: The position of the pivot point on the horizontal axis. (y) Axis: The position of the pivot point on the vertical axis.
