How does the bend tool (⇧ ShiftW) work? I couldn't find any mention of it in the wiki or in the new documentation.
When I tried to use it, I failed:
It seems to use 3D cursor position, as well as the angle and distance from the mouse cursor.
What do the Radius and Bend Angle do? How do they affect the result?
What is an example use-case of this tool in action?
