A new module has been added in SlicerHeart extension that can be generally used whenever a smooth surface patch needed that conforms to pre-existing anatomical boundary. By default a “soap-bubble” surface is created for the specified curve but the surface shape can be edited by specifying additional surface points in either slice or 3D views.
The module can generate an infinitely thin open surface, or a closed surface with specified thickness.
The module can also generate a flattened shape, which reproduces the shape and size of the 3D surface patch with a planar shape, with minimal distortion. This is useful as a cutout template for fabric (e.g., dacron mesh).
The module was originally designed for surgical repair of heart walls, but it can be used universally anywhere where a smooth 3D surface needs to be generated that conforms to the patient anatomy.

An example of an alternative application is generating bone flap models:
