- What's new
- Download the ArcObjects SDK for .Net from MyEsri.com
- Start Visual Studio, open the solution file, then build the solution. Be sure to open Visual Studio "As Administrator."
- Start ArcCatalog and select an appropriate network dataset to work with.
- Add a new restriction attribute to the network dataset.
- Set SelectionRestriction as the evaluator type for all participating network sources for this new restriction attribute.
- Start ArcMap and add your network dataset to the map.
- Click Yes when prompted, to add the network dataset's source feature classes to the map.
- Create a new network analysis layer and make sure that your new restriction is selected under the Analysis Settings tab of the analysis layer's property pages.
- Create a selection of the features that you want to restrict from your analysis.
- Solve your network analysis layer.
