Knot distance on path

[Joey Ponthieux <j.g.ponthieux(at)LaRC.NASA.GOV>]

Hello,
	I'm trying to get the distance along a path/curve that a specific knot
lies. I can do this via:

percentage =
Selection(0).ActivePrimitive.Geometry.Curves(0).GetPercentageFromU(3.0)


This will effectively return the U distance between the start and end of
the curve for the 4th knot of the curve. 


However, I'd like to be able to do this by defining the specific curve
without using the selection Object, something like:

percentage = crvlist1.GetPercentageFromU(3.0);


but this does not work. Is there a way to accomplish this, preferrably
using the OM?
