How to get length of pipes?
Almost no question should have an answer that writes out a whole model in textual form and then parses it just to look at one property.
The link route is available as the Link.points property value, which will be a List of Points in document coordinates. If your link is not a Bezier curve, then a good approximation of the length will be the sum of the distances between the consecutive points in the route.
