Add a shape with a lot of extra geometry (CVs or vertices).

Choose Surfaces->Sculpt Geometry Tool->option.jpg
This works with Poly or NURBS

Choose the Attribute Maps section

Look at your geometry, the image distorted it.

Go back to the first Sculpt tab, notice your shape was distorted by the max displacement and push or pull.
