Right click a connection to open it. Now select a poly-line table and right-click to import from it.
You should now specify which fields in your dataset hold each piece of information:
Allow loops should normally be left unchecked since loops are not allowed when doing routing. - If unchecked and there are loop links in data: They will be reported as errors in network_report.txt - If checked and there are loop links in data: They can be exported in one of the topology checking functions.
Finally set output folder, before:
Click the Execute-button
After you have imported a network, it gets automatically added to the list of networks.
If you started by cleaning the data, there should be no issues listed in the file "network_report.txt", which has been generated in the output folder.
Specific notes about importing from Folder connections
SHP files should have a PRJ file. Some SHP files may require that you specfiy the codepage, if the autodetection isn't possible. SHP files should be 2D ("PolyLine"), rather than 3D ("PolyLineZ / PolyLineM")
