I have a network of roads set up. It was working at first. Now, after adding a hierarchy and elevations, it's not wanting to reconize parts of my network. The interstate roads will solve, if and only if the stops are along it. Otherwise, if stops are placed anywhere, it won't use the interstate. I have the interstate as the top, then state highways, then major arteries and last local roads. I needed to include elevations due to many roads crossing over each other. They are not intersections, but bridges. I have called into ESRI support, but the tech is still looking/working on it. Has anyone had this happen to them too, and how did you get it fixed?
