Extrusion of 2D to 3D block following a curve
 

Hi!

I'm new using ICEM, and I need to make a multiblock mesh inside a curved duct. To explain it, I've tried to use the command 2D to 3D following a curve but the extrusion continues straight and didn't follow my curve. I'm not sure if my problem is clear, it's quiet difficult to explain :S. I hope somebody can help me please!!!Thanks by the way.
