My company designs water treatments systems for Commercial/Industrial users including Institutions, Laboratories, etc. Several of our Engineering friends specifying our equipment have asked us to use Revit. My question to the group concerns the value you may have for water treatment equipment designs provided in Revit Vs AutoCAD or similar program. I am looking for Pros and Cons as well as determining if the benefits equal or outweigh the cost and training.
Regarding keeping systems separate: If I'm connecting to a Plumbing Fixture or Mechanical Equipment type family, I don't have any problems with multiple systems. I had once tried to create my own "systems connector" family that I could use for HWR-to-HWS. That was what gave me problems. I think I made it a pipe accessory type family. But yes, I am talking mainly about vents (the ones that do not occur on the fixture) and hot water recirculation, both at the cold water supply side and the hot water end-of-loop side.

I've been using Revit since I graduated in 2011. The firm I previously worked for used Revit for MEP, Arch & Struc and Civil3D for civil work. We had everything in house and could live link models when the architects let us know he had updated. We also had disciplines in separate Revit files linked to each other. This helped keep the file sizes down, few crash errors from multiple users syncing at once and allowed us to make template files. The template files had everything each discipline needed to start a project including sheets set up.
The firm I now work for has been using Revit for a while but still does some things in AutoCAD (like details). I was brought in to move the plumbing department into the future by helping to develop better Revit standards, make families, etc. We're also working on training current designers how to utilize Revit for schedules so less mistakes are made.I gained 90-95% of my knowledge by being thrown to the wolves. If there was a problem, my previous employer would tell me to fix it and I would so what I could to do just that. I did read a few chapters from a book but forums and google were my best friends. I still go to them when I've got a tricky question. I also like to explore and see the things Revit can and can't do. Being a designer doing projects allows me to see what my company needs to be better.
I first started with an engineer who kept disciplines together. He later realized that having them separate allowed each designer on the project to work without interference from other disciplines or with fear of having their elements deleted. The company I currently work for has MEP disciplines in one model and while it's great to have everything in one place it bogs down the file when multiple people are working in it and can take a while to sync if everyone is doing it at once. Also, having each discipline separate keeps the file small and allows templates to be made where a designer has everything they need for their discipline and the file isn't very big.
As of right now, the details are being left in AutoCAD because that's what the designers are used to. I've cleaned them up and placed them in Revit and slowly getting designers to use them but change does come with a learning curve and when you're on a time crunch, it's too precious to waste on learning. I've got a template file designers can pull details and schedules from but the ones who aren't as Revit savvy are waiting until the last minute to continue doing things the old way. It'll change but it takes time.
My former firm was much smaller (12ish people) and had all disciplines under one roof. The firm I work for now is bigger (100ish people with at least half being designers or engineers). Making changes aren't as easy as an email being sent out and everyone abiding by it. I'm getting there, though. I've dumbed down a lot of models to just introduce designers to placing models and scheduling them.
