# How to get a “smoothed” wireframe using Freestyle lines?

Let's say I have a cylinder. When I turn on smooth shading and auto-smooth, the side edges are smoothed out like this:

So the question is, can I do that on wireframes? I mean I want to hide all the smoothed edges, leave the outline and sharp edges alone like this:

I guess some eevee shaders could do that but I don't know how.

• Hello :). You might be confusing normals and geometry. Normals can be smoothed, but geometry stays the same. – Jachym Michal Apr 1 at 6:41
• Thanks for explaining...I know geometry won't be smoothed. I just want those "smoothed" edges to disappear in viewport or render result. – Liuuzaki Apr 1 at 6:59
• @Liuuzaki In the viewport, you can play with the "Wireframe" threshold slider under the overlays menu. – Will Chen Apr 1 at 18:15

If you use Freestyle, one of its parameters is 'Crease Angle'.

If you set that high in Freestyle's general settings, and one of the discriminants for the Line Set is Edge Type > Crease, then Freestyle will pick up edges between faces where the internal angle between them is below the given threshold.

There is a 'Face Smoothness' checkbox for the Crease Angle. If it is unchecked, it will use the angle between face-normals in the underlying geometry. If checked, it will use the normals as interpolated by the smooth shading algorithm...

...above, with 'Face Smoothness' checked. The left cylinder is flat-shaded, and the right cylinder smooth-shaded, with Autosmooth set to split out its caps.

There is also a Crease Angle modifier available for attributes of the Line Style. So you can, for example, vary the color of the line, depending on the angle between the faces it separates:

You can always render out Freestyle as a separate pass, to composite with other components as you choose.

I've done some research and I found this nice free, non-photorealistic render engine. By using one of the sample materials, I got the following result and it's a realtime one!
