Is there a way to set an absolute size for the curve tube brush?

I am trying to draw uniformly sized thin tubes on an object with the curve tube brush. If I change the size of my view of the object or even just rotate the view a little the size of the tubes I am drawing changes. Is there any way to set an absolute size for the brush so that the strokes will be the same size no matter the size of the view is?

Thanks,
