+The \b Length defines the position of the point on the given edge. It

+is extrapolated along its curve (except for bezier and b-spline
+curves). 
+The <b>Start Point</b> defines the direction for the length
+calculation (if not defined, the first vertex of
+Edge is used, else the vertex of Edge closest to StartPoint is used).
