Is it possible to transfer a direction of polylines to another set of polylines?
I have a road network with "oneway" column in it. I do a series of operations on the network in ModelBuilder to prepare it for further analysis with Network Analyst (I am using ArcGIS 10.4).
However the direction of polylines is messed up (particularly after using "Unsplit"--"Feature to Line" tools).
Can I somehow extract the directions of initial lines and transfer it to result lines?
I can not do this manually, because the network is pretty large.
Maybe extract start-end points first, but how can I assign them to polylines as direction?
On the picture below: the red arrow is the original direction, the black arrow direction I get after using some tools in ModelBuilder.
