What are Feature restrictions in UN

[MohamedIsmael]

What is the purpose of Feature Restrictions, and what is the difference between Feature Restrictions and Network Rules?

For reference, from the help topics

Feature restrictions and rules—ArcGIS Pro | Documentation

perhaps those using UN can provide more concrete examples from their situations

Hi @MohamedIsmael , 

The feature restrictions are system defined rules that dictate how different elements in the Utility Network can interact with each other. These are set rules that cannot be modified.

This is not to be confused with Network Rules. Network Rules provide the next level of control. 

The Feature Restrictions come in different categories like - Geometric Coincidence, Connectivity associations, Structural associations etc.

An example of this is - Connecting Electric Lines to Poles (Structure Junction) 
Structural attachment is not possible between  the line and structure junction directly.
But looking at the matrix we can see that a structural attachment can be created for a Structure Junction and Electric Junction. and the electric junction can be placed on the line.

Hope this helps 🙂
