I also have a similar problem with the extrude rotate tool as ishan. I tried your method method of 'extrude mesh', but for it to work, I have to generate the unstructured 2d mesh and when I rotate the mesh elements, I don't have the said grading on the edges. But, the big problem is, I don't have blocking on the extruded mesh either. And I need this blocking to extrude this mesh to the farfield.
Is there something that I am missing here?
