Geometric network support is available in core ArcGIS. How are you trying to see them? Do you have some data with geometric networks? Can you use Catalog to view it? Can you add the data to map? There is a toolbar titled "Utility Network Analyst" that you can bring up that will let you work with analysis on these geometric networks. If you have installed the tutorial data, try going through this tutorial: Exercise 5: Build a geometric network—ArcGIS Help | ArcGIS Desktop Jay Sandhu

Are you able to route to all the stops? And without looking at the data/layer, it is hard to say what is going on. I suggest that you call Esri Tech support so that we can follow up by getting your data and diagnosing it more. Jay Sandhu

You can do a service area to check for connectivity issues. Create a service area layer, load your depot as the facility and set the service area layer properties to generate lines (instead of polygons), then set a large break value, say 120 minuutes and solve. Are all expected streets within the 120 minutes traveled by the service area? Or you could also load all your orders as stops in the route layer and see if all can be reached. Jay

If you are not able to load the locations by geometry then there is some problem going on with the network dataset or some settings like a spatial reference or search tolerance on the VRP layer. What I was suggesting you to do is create a new Route layer, click two stops on the map and solve. Does that work? It would test that the network data is built correctly and that you are able to add locations by geometry. Jay Sandhu

>I reloaded the orders based on geometry and Recalculate Location Fields - Unlocated (913 orders) What does this mean? Did you relocate location fields and still get 913 unlocated OR did you load the orders again by geometry? Are there other feature that need to be loaded again? Like depot, barriers, etc.? Can you test that you are able to solve a route on that network dataset. And you can you try creating a new VRP layer and adding the orders/depots/route and resolve. Jay Sandhu

It is possible that you are loading these points with network locations. That is, the input point feature class has the network location fields such as SourceID, SourceOID, etc and it is using the old, stale locations. If that is the case, make sure to load by geometry. OR you can in the NA Window, right-click on the Orders and choose to Relocate All to update their location on the network. Jay Sandhu

Not clear what you are trying to achieve. Are you trying to solve the k-shortest paths between one origin and one destination? How does it relate to closest facility? Jay Sandhu

This is as designed. If you can reach the area from all sides then it is "covered" or "served" by that facility. The actual output of a service area solver is all the lines that can be reached from the starting facility. Turning that set of lines into a polygon needs a purpose. The main purpose of a polygon is for demographic analysis to answer questions like how many people live within 5 minutes of this facility. For that you need to intersect the service area polygon with a population polygon and get percentage covered to get population. But if you want holes like you show in your picture, then I suggest you use the service area lines and then run the Buffer tool with the Dissolve All option. See screen shot below for the difference between Service Area polygon and Buffer. Jay Sandhu

What software/version are you using and what settings are you using for the service area. As Joe mentioned, post a picture of a problem and that might help figure out change in settings. Jay Sandhu

Each facility can have a different break value. You can use Load Locations to load the facilities from a feature class and then map a field to the "breaks_" value. See screen shot that shows a field called ServiceTime being mapped to the Breaks_Minutes. You can also do this with the GP Add Locations tool. Jay Sandhu

What are your route analysis layer optimization settings? That is, after you add the first stop, a second stop and then the first stop again, are you solving for best order? If yes, then it will redo the sequence and visit the first and last stop at the same time. You should set it to preserve first and last. Generally for each unique route name, the stops are visited in sequence order. So each route for every unique routename can start and end at the same location not just one only. Jay Sandhu

Joe, The NET2CLASS > 1 will not locate on any feature that is a highway. It was an example of what/how a query could be specified. If you have data that does snap on highways, you should use some other type of query based on your data. But if your application is residential deliveries, then excluding features of type ramps, highways, etc., should be useful! Jay

You can control the stop locations by specifying a query on what line features to exclude. To do that, on the route analysis properties, click on the Network Locations tab and then in the Snap To area, right-click on the Streets feature to bring up the Build Query dialog. Then specify the query. For example with the San Fran tutorial data, I could specify NET2CLASS > 1 to not locate on any highway. You can read more about this capability in the "Snapping environment with Build Query" section here: What are network analysis objects?—Help | ArcGIS Desktop Jay Sandhu

In your case, the most efficient method is to bake this into the network dataset. So add a new FT_ LocalDelay and TF_LocalDelay fields on your streets feature class and calc them according to your needs (i.e., old traveltime + 5 seconds for local roads) and then in the Network Dataset, define a new impedance attribute called LocalDelay and set it to your new fields and rebuild the network. That way you will get the best performance. Jay Sandhu

There are numerous options for "delays": Network Analyst can apply delay via barriers. Barriers can either be point, line or polygon. They can either restrict or scale cost of the existing network feature. So you could add a line barrier with a scaled cost of 2 and it means it will take twice as long to go through that edge. Network Analyst also supports real-time traffic feeds where you can get the exact slow down now and compute a path based on current travel times. It also supports historical or predictive travel times based on what your network dataset supports. You can always recompute the travel time to be based on expected slow down and re-build the network dataset with these values. Jay Sandhu
