Spline object on a spline path

By looking at the parametres names, how they are used in Curvy's code, and fiddling with them if needed, you should be able to understand how it is used.

I did but no success. Seems using FloatRegion attribute itself is not enough! Should I create Editor script for my class and inherits CurvyEditorBase ? (Although I tried to this too but still no success)

Also why From and To value in Range tab in ShapeExtrusion is not same as Position in SplineController ? Same value of From field of ShapeExtrusion is not same as Position of SplineController.
