Models built in ArcMap should generally just work if you run them in ArcGIS Pro.  For any more detailed help on porting stuff into Pro, you might need to contact Esri Support.  They could also help you debug your ArcMap service area problem in more detail.  Be sure to show them this thread. ...

Did you switch your polygon type from Generalized to Detailed at some point? I just tried it, and Detailed gives me 0-20, but Generalized shows 0-[individual maximum].  This is probably a bug, which I will investigate further and log. ... View more

Okay, sounds like you haven't identified an obvious change that caused the problem, so let's talk about what you're really trying to do and see if there's another way you can get the result you're looking for. From what you've said, it sounds like you are trying to assign territory to the closest fire station.  In other words, you're not creating a 20-minute drive-time polygon around each fire station.  Instead, you're setting the break value to 20 minutes, but you want it to return a polygon showing a maximum of 20 minutes, but if there's an area where those 20-minute drive-time polygons would overlap, just assign the area to the closest fire station.  When this happens, the ToBreak generally will end up as something less than 20 minutes if your fire stations are pretty close together because there was nowhere that the fire station's service area got as far as the 20-minute break.  It always ran into the service area of another fire station first.  Do I understand this correctly? I guess before speculating further, make sure your Service Area polygon generation settings are correct. Check the  information in the "The Polygon Generation tab" section under the "Multiple Facilities option" on the Service Area analysis documentation page.  If the output described above is what you want, you should be using the "Not overlapping" option. Also, if you describe in more detail what you're really hoping to analyze, we might be able to find a better overall way to do it.  Feel free to elaborate. ... View more

Yes, you can use the Global Turn Delay Evaluator on your network dataset to establish a delay time for every intersection depending on the direction of turn (left, right, or straight): http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/global-turns-establishing-global-turns.htm ...

You said the results have changed in the last month or so.  Did you do any of the following: - Update your ArcGIS version - Edit your network dataset - Change your model or procedure Something must have changed in order for the results to have changed.  Let's see if we can figure out what it was. ...

Are you solving your service area against a local network dataset, or are you accessing the ArcGIS Online services to solve the service area through ArcMap? ... View more

Can you add more specific details about the analysis you're trying to solve and what the error message says? Question 1: You said you're using ArcGIS Online.  Are you using a location-allocation layer in the map that uses ArcGIS Online as the network data source and then hitting the Solve button on the ribbon or using the Solve geoprocessing tool?  Or are you using the Ready-to-use services Solve Location Allocation tool? Question 2: Is that ALL the error message said, or was there more stuff up above that.  Please paste the full text or add a screenshot. Question 3: How long did the analysis run before you got the error? ... View more

If you're working with python PointGeometry objects, there's a method called angleAndDistanceTo that can be used to calculate the bearing from one point to the next. PointGeometry—ArcPy classes | ArcGIS Desktop  ... View more

No, I don't think that would work.  In this case, the user knows the value he wants but needs a way to inject that value into the Network Analyst layer's properties.  We just don't provide that capability in ModelBuilder. ... View more

Hi Sam.   This work is currently in our plan for ArcGIS Pro 2.4.  If we don’t hit any roadblocks (or polygon/line barriers that slow us down ) we should see it in the mid-year Pro release.  If it slips for any reason, it should make it into ArcGIS Pro 2.5 scheduled for the end of the year. This note should be treated as an estimate, not a promise. ... View more

Okay, good luck.  I personally will only be at DevSummit on Friday morning, but various members of my team will be around all week if you have general Network Analyst questions. ... View more
