Unroll rurface in Rhino

[Broen]

When I chose surface to unroll the program only respons: Select curves on surface to unroll! And nothing happens - whats wrong

You have to press enter on that question.
Yiu have the possibility to select curves for a cut out for example, but you can press enter to select none.

My mistake was to have an almost similar object placed at point 0,0,0 so I could not see the new one
