>> Bending is not more in the spirit of Polygons Modelers?
As propagate is in Nurbs spirit, you should not need to make that!
If yes, it's because your start concept was not enough elaborate :)

I don't really agree but maybe I don't understand you.
It's often easier to work on some details on a '2d' plane/view and then bend it, that dealing with a curved surface.

Was maybe thinking to tire pattern for example ... or any kind of engraving job.
