Rendering DWG line

hello, i have a quick question.
In the past i used 3ds max and i was able to make Spline renderable.
Is there a way to make something similar in sketchup using Vray?
I import a .DWG in my scene for reference but i would like to see it in my render. right now it doesnt show.

thanks

Generally renderers require a face for an object to be visible. One thing to try might be creating a simple face, perhaps a circle with not too many edges, and use the FollowMe tool to extrude the spline into a small tube.
