RE: [EnergyPlus_Support] Re: Controller error messages
But it only shows objects and how they are connected.
It doesn't (yet) show the nodes (they are implied as
the connections between objects).
And if there's an error in your file, it might not create
the SVG.

Perhaps you missed the tool HVAC-diagram.exe that is distributed with the
current release.
It should be located in the directory ..\EnergyPlus\PostProcess\ . It
processes output from EnergyPlus and makes a .SVG file that diagrams the
main parts of the HVAC system.

Thank you, Linda.
Another question: in a previous post you mentioned an in-house
version of E+ that shows the node-branch-loop connections. I spent so
much time trying to get these straight in this model. Will a utility
program like HVACDiagram be coming out soon?
