get world vector3 from absolute position on spline

[hawken]

Hi, I thought this was TFToDistance but I'm after something different.

I know the absolute position of an object on a spline, I want to get a world space position of a fictional point along the spline. For example my object is at absolute position 55, I want the vector3 of +10 length along the spline.

Is this possible without placing another spline controller on the spline?
