This topic has been discussed before on this forum - keeping a piping system in Revit small for speed. My question is how do you all go about that? From what I see, there are a few way to go about it:
1) Simply leave an open end on a small portion of the system (ie. bathroom group), the pipe then going to the mains (but not actually connected to the group) would need to have the "Additional Flow" parameter set to be identical to the total for the group.
2) Create different piping systems for portions of the building - CW for enlarged plans, CW for mains, CW for Mechancal room. The flow would not propagate though and would need to be set similar to above.
3) Create a Mechanical equipment family containing connectors to allow pipe to connect in, then a connector for flow to go out. Again, you would have to manually match the flow rate, this time through a parameter in the family.
All of these approaches have their drawbacks and there's part of me that wants a nice, completely connected system. There's a bigger part of me that wants Revit to respond more quickly when editing pipes. So what is the solution? Or at least, what have you found that works best? Thanks for the input.
