[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.
