To create a wire deformer, use the Wire Tool. The characteristics of the wire deformer you create depend on the Wire Tool’s tool settings. By default, the Wire Tool is set to create a wire deformer without holders.

The Wire Tool menu item is located under the Create Deformers menu in the Animation menu set ( Create Deformers > Wire Tool).
Deformation Order
Specifies the placement of the deformer node in the deformable object’s history. Placement selections include: Default, Before, After, Split, or Parallel.
Specifies whether the deformer set will be in a partition. If a deformer set is in a partition, the points in the set cannot be in any other set. The result is that only the deformer you are about to create can influence the points. If on, the Exclusive Partition and Existing Partitions options become available. By default, Exclusive is off.
