You have got more patience than me. I have tried to use these tools to generate (basic) network diagrams and by the time I reached your third step I already knew that it was time to quit and draw it out myself. Diagrams need to be correct and accurate otherwise they're just art. I also need any amendments to be made to the same diagram, not to have it regenerated each time.

I do like the idea of another commenter here who takes a photo of their whiteboard and instructs the AI tool to turn it into a structured diagram. That seems to be well within reach of these tools.
