Revit - Sweeping and Reference Points

Main Topics
    Sweeps
    Reference Points on a Line
    Direct Manipulation

In this Revit Architecture 2010 video we cover the new way to make sweeps in the conceptual mass environment.  Like all the other methods, the tool intuits the operation based on the selection you give it.  In this case I feed it a path and a profile and knows to make a sweep. What do you think of this approach. At first I was a bit skeptical, but now that I have been using it for a while it's really growing on me :)
