[Gmsh] Problem creating surface

Hello,
I need a mesh for BEM analysis. I created the part with with FreeCad 
(cad.png) and imported the step-file into Gmsh. That works fine. Some 
surfaces were already created. Now I tried to create the surface for the 
small tube, but I got only the surface of the opening of the tube not 
for the wall (mesh.png).

What have I to do for it. I choose 'Add/Ruled Surface' and selected the 
nurbs and the line between them.

Thanks
Maik
