Step-like curved surface that should be smooth. (see images)

I have used the rail revolve command on a simple set of profiles. The curves being smooth and fluid on the profile are then translated to a rigid/step-like surface when the command is complete and the surface is built. I need this to be a smooth surface like the curve. I’m not sure why it’s doing this, any help/advise would be greatly appreciated.

Just guessing, but it looks like a mesh setting that could be adjusted. —-Mark
