I've bulit a network dataset with existing streets and a fictional highway.
The problem is very strange to me. When I create a "New Route" and pick two points, the route does not drive along the existing edges in the network at one part of the streets (image below).
I do not know how to solve this problem. It's also interesting, that the shape length massively changes in the network, but I've created a field called "meters" to avoid and handle this problem (the field has been calculated before the network was created).
Furthermore, when I try to build the same network and create a route at a PC in university, there's no problem with the route guidance...
I'm very interested why this problem shows up, hope someone knows more about it.
