[EnergyPlus_Support] Re: Controller error messages
HVAC Diagram is a great presentation tool but it doesn't help debug a
model, which is where I see it's greatest value.
WinEPDraw has the same issue; it would be extremely useful if I could
see and edit the surface vertices. I was unlucky enough to have a RA
plenum in my model, too many surfaces, not enough time.
