One Line Diagram with Dynamo

I was looking through the forums and there’s very little topics on One Line Diagrams using Dynamo. I was wondering if this is possible to do? I want to know if things like using dynamo to create a summarize calculations for one line, Populate Single line with feeder sizes and also Getting voltage drop calculations automatically?

Thank you for your time and replies.

Can you send some screenshots (directly or through DropBox or similar)?
