Josh, do you happen to have the LGIM graphic data model?
Here is probably the best thing I found for this 40585 - Data Models
Not sure how helpful that is, I think this is old technology that Esri doesn't really support anymore.
you, Sir, are a kind man.... in my current state, it will indeed be helpful. i tried to use diagrammer to obtain the LGIM graphic data model and failed miserably, but i need to understand how it works so i can modify the code for the water utility network editing tools and get them to work properly with my own model. as you can see, i'm way out of my league (don't tell my boss)
The Data Dictionary created by X-ray may also be helpful to you in this case. Not graphic but still useful

James, i'm new to this and frankly didn't understand much of what you said.... i just downloaded the LGIM and installed diagrammer to obtain the graphic data model because i'm not interested in adopting the whole model but in getting the water utility network tools ESRI has to work with an existing model i'm trying to enhance...
if you could be so kind to share the LGIM graphic data model with me, i would really appreciate it.
