Utility Network tolerance value

[OliviaGill3]

How are tolerances set in the Utility Network and is there a default value. And if possible how can these be amended?

Any info is appreciated.

@OliviaGill3 Tolerance and Resolution for XY, Z and M are set based on the spatial reference at the  asset package schema of Utility Network. These settings are preserved when configuring the Utility Network by 

• Stage Utility Network—Creates the utility network dataset
• Apply Asset Package—Configures an input utility network using an asset package

The XYZM tolerance and resolution may be modified using the Change Asset Package Spatial Reference tool that is part of the Utility Network Package Tools to automate the process of creating and configuring a utility network using asset packages for specific industry domains.

While @AyanPalit is correct about being able to change the XY tolerance and resolution I would caution you against changing these values because they are permanent, and they can have unexpected consequences.

If you're having issues with features not being connected in your network because of the resolution/tolerance of your source database, then the recommended approach is to include a process to snap and correct these features during your migration to the utility network (using FME or geoprocessing tools). This gives you an opportunity to experiment with different snapping tolerances so you can find the right tolerance that minimizes topology errors and manual cleanup, while also maximizes the number of features that are connected (appropriately).
