How to simply uniform curves in nurbs?

Hello everyone,

I have imported a stl file, in mesh. And I converted it into nurbs for further editing. I tried many commands but still can’t simply the curve. It is not a complicated form but just a uniform geometric curve. How can I simply that?

Hi -

What you perceive as a curve are the edges of a bunch of surfaces. There is no automatic reverse engineering of meshes to NURBS in Rhino. You can use the Circle command with the 3Point option to create a new curve and extrude that to create a new surface.
