How to cut a NURBS Surface using a NURBS curve?

[magneto]

A surface like this that has thickness (like a pipe):

Can I cut it using the yellow NURBS curve, so I can keep either the top part or the bottom?

Thanks

Is this what you are looking for?

Thanks man, that's very close and taught me a few things. But I was actually trying to cut the pipe using a closed curve. So I changed the curve in your scene to a closed one and bypassed the extrude and it didn't work after that.

Do you know if this can be done?

Thanks man

Closed in what sense? As if it is revolving around the pipe or like a tube crossing the other tube? It is not really clear what you mean, can you clarify?

Sorry I meant the curve basically that has no start or end, and surrounds the pipe itself.

So something like this:

Just convert a curve to a NURBS surface:
