How to change line width in rhino default renderer?

Hi, I’m just trying to render a model that has some lines on it as a way to represent details. But when the render finishes, the lines are really thick and stand out way too much in the render. Is there a way to change this thickness like there is when using the “Print” command?

can you show an example?

Ah, while rendering a higher resolution example to show you, the problem fixed itself.
I guess while I was rendering at lower resolution for previews it made the lines seem thicker than they actually were.

Although it would be nice if rendering used the same line weights as print.
