Distance On line

Feb 8 at 8:56 PM
Is there a function like DistanceOnLine or PointAtDistance for a Polyline? I cannot seem to find any information on how to get either.

What exactly is this function supposed to do?

I would like to give a distance on a line and have a point on that line returned. An the reverse of that as well, give a point on the line and have it return a distance.

This is all done in a service, without the use of a map. (That will come later in the process). With that as well, I think I saw a "nearest point on line" ?

I think DistanceOp should help you do that.
