Hi,
I read here (https://pro.arcgis.com/en/pro-app/2.9/help/data/utility-network/coincident-features.htm) that some objects in the UN data model are allowed to be coincident, for instance :
"Feature from the Assembly class coincident with another feature from the Assembly class"
But in my case, even with snapping enabled, I cannot snap an assembly feature when trying to stack another assembly...
I also tried to create a junction-junction association between assemblies, but it is not permitted.
Is there something I'm missing ?
