After dissolve network, you need to Build Network. Else it will say 0 features as the network has not been built yet. And yes, it can reduce the number of features by half.
I have just discovered the network dissolve function and I have managed to run it fine.
However I have some questions.
My original network has as its source an edge feature set (call it EFS) which had some custom fields such as the name of my roads.
The output of the dissolve network produced a copy of that feature set but with some of the original fields missing including the name of my roads.
Now how do I bring back the new network (the output of the DN) to the location of my old network without losing any information?
I would like the new network to be linked to the unaltered EFS and not to the incomplete version.
I hope I am explaining my problem clearly.
