simple NURBS extrusion question

[David Gary]

Hi.

Sorry I'm facing a little newbie problem

( bcoz i rarely explore the nurbs sops and largely prefer the Polygon-Subdivision scheme)

I'd like to extrude a NurbsCurve Profile/X-section along a NurbsCurve path.

The Skin or Sweep Sops make copies of the NurbsCurve Profile ( at each Path CV) and then put a skin. So the result is not smooth ( linear junction between each copy).

It usually satisfies me because i don't need too much precision but here

i need a smooth result

I'm sure there's a simple way to achieve a smooth result but i cannot find it.

Any help appreciated.

( i feel abit ashamed not to know my sops all by heart).

append a skin to the sweep. Keep output geometry off for the sweep. I don't see why you're not getting a smooth result.

You could also increase the order of the backbone curve or even refine it before sweeping

sometimes the OGL viewport looks a bit jaggie but renders fine

That was EXACTLY my problem.

To have a better interactive display i used convertToPolygon -> Subdivide

But Is there any NURBS display options ( like in Maya) ?

There's a few places to change your LOD. Off the top of my head, hit 'd' with your mouse in the viewer. There's a Level of Detail setting somewhere in there.

Yes, edward is right. go to your viewport display options (the + mark on the right) or hit d. Under the viewport tab, there is a level of detail slider. that will adjust your ogl nurbs viewing.

hth,
