Rough booleans please help!

So here's my problem, I'm working with nurbs booleans and getting some strange results. I am trying to get a clylinder that looks like it has some thickness, like a pipe.

So, I take a nubs cylinder with a cap at one end, then duplicate it, make the duplicate smaller & do a boolean. That all works fine, and I get the general shape that I want.

However, when I go to render the scene I see that after the boolean opperation the edges of my pipe are no longer smooth. Now it looks more like a hexagonal pipe. I can see creases all along the edges where the CV's are.

Is there an option in the boolean operation that I am missing or is there some way to reverse this and have a smooth surface again?

Any help would be really apprecited, I've looked through the manuals to no avail. Thanks,

hey, suss out nurbs tesselation (you'll find it in rendering surfaces sectn of maual i think, and in the tesselatn options area of your surface node in the attrib editor). play w smoothe edge to help localise the tesselation around your boolean trim edges.

NURBS booleans for that are massive overkill. You just need an inner and an outer cylinder, and you can duplicate curves from the ends of them and loft them together for the edges.
