Rendering thin rope

Hey guys ive read some tutorials on rendering rope but they all involve creating really detailed ropes that follow paths etc. I need to render a really thin rope, in the final render it’d just appear as a pixel or so thick line. Whats the best way of going about this?

There’s the method used to make cables.
Use a bezier curve for the cable.
In the curve settings enable:
Fill = Full
Curve Resolution = smoothness of the curve
Bevel Depth = thickness of the cable
Bevel Resolution = reolution of the cable cross section

looks great thanks mate
