    Physically separated but in the same system?

    Hello guys, hope you are having a productive week.

    I'm currently trying to solve an error in a project where I have two physically separated duct branches which are somehow in the same system. If I change the system of the first branch it automatically puts the second branch in the same system and vice-versa.

    I already tried to divide systems and it helped me with some of the branches but there are a few of them which I can't separate. I also tried to delete the air terminals and mechanical equipment to leave the ducts disconnected but they still change the systems together. I tried to use the "remove from system" tool but it doesn't allow me to select anything in the drawing.

    The problem is that I am assisting a colleague in the project and I don't know what caused this issue.

    My questions would be:

    1.) What usually causes this problem? My only theory is that it could be because some of the equipment was copied and it stayed connected to the original system.
    2.) Is there a possibility to break the connection between these branches?

    Thank you in advance!

    Yes its because there is Air Terminals, Equipment or Plumbing Fixtures that have already been added to a system. If you just copy pipes a new system gets created each time.
    If 'Divide Systems' doesnt solve this for you then you could try TAB until you select just the system (Dashed line) and delete it. This will make the system for all the pipes 'Undefined', so then draw some new pipes to recreate the system type.

    Revit didnt used to do this, every separate, unconnected set of pipes automatically became a new system. I guess some people got hung up on everything having to have the same System Name rather than just using System Types and letting revit name/number things how it likes...

      This is exactly what I was looking for. I knew you could select a system but I didn't know that you can delete it like this. Thanks a lot!
