I have a model that does a number of steps to a state wide road network. I've confirmed that all the way through the model, the generated data maintains integrity, but after running a final Pairwise Dissolve, gaps of roughly 0.7-0.9 metres wide are appearing randomly (not many) between the start/ends of some line features (image below). Any idea how I can prevent this?

@AlanHatakeyama That worked a charm. Thank you for your help.

Thanks for the help. I hope to see something come through on the other case. We don't really want to have to republish all our feature services with old split policies to make them comply with the new versions of Pro! It would make sense if we could update that setting in ArcOnline.

Hi @KoryKramer. Thats good to hear. I'm still on 2.8.3 because we have found issues with 2.9 that are yet to be addressed and negatively impact our workflows. Topic here: https://community.esri.com/t5/arcgis-pro-questions/splitting-tool-wipes-values-from-agol-feature/m-p/1131937 Support case number #03005678

Great idea!

I'm trying to write a Field Script in my Network Dataset Properties that limits a Travel Modes ability to use edges that don't contain specific attributes. For example, a feature with a column called RAV3_NETWORK either contains a value "Tandem Drive Network 3" or is NULL. I want to prohibit a route from traversing edges where that field is NULL. I have managed to get this Field Script to work: NOT([RAV3_NETWORK] = "Tandem Drive Network 3") where I have added in another random value instead of NULL, but I don't want to have to modify the data to do that. I would rather use something like: NOT([RAV3_NETWORK] = "Tandem Drive Network 3") OR [RAV3_NETWORK] IS NULL which would find any value that isn't Tandem Drive Network 3 as well as return the Nulls - but I can't for the life of me get it to recognise Nulls. I've tried Empty, IsEmpty, IsNull as well with no luck. The above query returns this error in the Build Network log for each feature with a NULL value: SourceName: State_Road_Network, ObjectID: 354, Network object evaluator error.

I've been using the Dark Theme in ArcGIS Pro for a while now and have gotten quite used to using it. However, when building a Network Dataset, there is one window (that I've found at least) where there are black text fields on the dark themed window background. See image below. The text in the Type and Usage Type columns is extremely hard to read until you click on a cell and the text colour changes to white on a blue background (below). Why can't these fields display the same as all others in all other windows (white text on dark grey background)?

No solution yet - we've just reopened the ticket with ESRI. Hopefully something will come of it. Nice to know we're not alone though.

Hi Brains trust - we've just done a test install of 2.9.1 and this is still a problem. We can't see find a way to change the Domain Split Policy for an ArcGIS Online Feature Service from Default to Duplicate. When we split a feature through ArcGIS Pro we lose the attributes in any field that has a domain applied. Why this wasn't a problem before but is now is beyond me. Surely there's others out there with the same issue?

‎02-01-2022

Yeah. I did consider trying to use the elevation fields, but decided against it as it would have been too much work to attribute all the required features in a reliable manner (it's a state-wide dataset). Unfortunately it's not my data and our State doesn't have a routable network source available (the data was setup for asset management).

Thanks for the links. By the looks of it, there's no way of mass creating this type of data - it must all be done manually (not what I was looking for unfortunately). I was looking for a way to solve many overpasses turning onto the underpasses instead of taking the on/off ramps. I did manage to come up with a solution though. I did a once off pass of the data identifying the overpass or underpass I didn't want turns to happen on, buffered the segments 5 metres into a polygon feature class (yellow features below), and in my network building process, use those polygons to spatially select any segments (wholly within) and create one line data source, and then repeat it selecting everything else (wholly within inverted) to create a 2nd line data source. Both of these line feature classes are then used to build the network, but the one containing the no-turn features within the polygons are set to an Endpoint policy in Group Connectivity, whilst the rest of the data has an Any Vertex policy. Where the datasets meet, turns occur (valid intersections or connections), but when crossing an over/underpass, turns won't happen.

I'm using Network Analyst to build a road network for finding haulage routes. Unfortunately the data I'm using was not designed for routing, so I'm having to manipulate it a fair bit to get what I want. One issue I'm yet to resolve is how to deal with turns at junctions that shouldn't exist. In the screenshot below, the junctions in the green circle are actually an overpass/underpass scenario. I know I can delete the vertices to stop a junction forming, but this is proving difficult to automate because in some instances the vertices are the start/end of lines and then a break forms in the lines. Instead, I'm sure there's a way to prevent a turn occurring at a junction but I can't for the life of me figure out how it all works. Do I need to create a Turn Feature Class? If so, can I just populate it with segments (like below) and somehow set that as restricted in the Network Properties? Is there another way? (I wanted to delete the junctions after they were created through a spatial selection but it's not editable).

@HuubZwart turns out it was the replicas. I disabled editing on one of the layers (in preparation of republishing it) and the size dropped to 21MB. There were over 133 copies of the data in offline mode. Didn't bother republishing it - just reenabled Sync. Thanks for the tip.

Also just found this (https://gis.stackexchange.com/questions/227115/remove-polyline-vertex-outside-polygon-in-arcpy) from 5 years ago so will see if I can make it work. I've got a trial of XTools Pro which gives me the Line to Point option, so at least I have something to play with.

I've just found this post (https://gis.stackexchange.com/questions/227268/delete-line-vertex-from-polyline-layer-using-point-feature-in-arcpy) that leads me to the Feature Vertices to Points tool, which might have been helpful in a larger convert, select, rebuild process, but I don't have access to an Advanced licence (only Standard).
