That looks like a really good enhancement to formz.

While the sub'd tools are nothing special the utility to convert them to nurbs surfaces for further Boolean operations is really cool. Pity the video didn't demo it on a complicated mesh.
Also having the ability to work with both meshes and nurbs surfaces all in the one application speeds things up a lot and takes out some of the complexities of transferring data from one app to another and learning two pieces of software.

One thing put off buying formz when it was recently on a special price was that you can't loft to a point. It has about zillion ways to loft and create shapes but can't do this one simple thing.
