We need more piping systems, such as- "Tempered Water" (works like Hot or Cold, using "Other" doesn't work) systems and connectors, and Hot Water Return (loops back into Hot Water) systems and Connectors. Maybe even Soft Water, but I think I can work around that.
I tried a Recirculation system, The Recirculation pipe goes from the "Hot water system" to the "Cold water system", just before the Water heater. This doesn't agree at all with the Revit MEP systems. Even if I loop the return within the hot system, the flows go away completely. This would need to be worked out in order to connect everything up properly.
I know if you go to the MEP Settings, you can create a new "Fluid Type" and give the Temperature, Viscosity and Density, but the flow characteristics and the fluid behaviors are different with steam and refrigerant.
We definitely need Steam and Outside air Connectors, Systems, and Flow parameters. Autodesk, keep in mind there are multiple different steam systems, too, varying in pressure!
Medical Air system
Medical Vacuum system
Medical Nitrous Oxide system
Medical Nitrogen system
Medical Oxygen system
Medical WAGD system
Carbon Dioxide system
Sanitary Vent system
Hot Water Return system
DI Water system
Storm Drain system
Natural Gas system
plus an absolute shit ton of more parts included for Plumbing/Medical
This guy knows how we do. I hear 2011 is coming soon, no comments specifically on content due to beta program confidentiality agreements, but the word is good. we'll see. we all have high hopes, Autodesk!
