Why do I get large bevels on a curve with such a small bevel object? I am bevelling a simple circle with another simple circle and as you can see from the screen shot below I have to make the bevel circle incredibly small and I still end up with a very large cross section. I don't understand why the cross section on the bevelled curve isn't the same size as the bevel curve.
You will have to :


apply the scale Ctrl+A
select all point of the curve and reset the radius back to 1 :




Note : to avoid applying the scale just set the radius to  1/scale
