Using Split Area Features to Define Deformation Areas
You can use a Split Area feature to define a deformation area for an unbend operation. A deformation area acts as a bridge between a multidirectional bend and the outside edges of the part. The deformation area must be tangent to both the deformed surface and an outside edge. First create the Split Area feature, then select it as a deformation area when performing the unbend operation.
 
* You can add features to split areas after they are unbent.
