sheet metal development in drifting

[domy04]

hi to all, and recently I've been using nx version 8 after various puzzles solved also thanks to this forum, now I can't insert the pavement and/or development of a sheet in the drawing board, in sw there was the configuration that I could choose when I inserted the view, but in nx I don't find useful commands, you can help me, thanks

Then I answer myself, as I solved,
nx sheet metal
1 sketch
2 converts to sheet metal
3 development plan.
now in drafting you can choose whether normal view or flat pattern.

But I wanted to ask where the rays and bending factors change?
