In this video Nx 7 Freeform Modeling - Synchronous Technology tools are used to convert a simple rectangular 3D block in to a product. How the simple features such as Sketches, Extrude & Blend are to be morph into more complex organic shapes. Freeform features also recognizes geometric conditions such as symmetry & offset. Blends can be quickly defined & modeled. Tools used are Press-Pull, Define Parametric Curves, Freeform editing.
This can be seen in more detail in following video:
