How to change a pipe to different system name?

[bwang-tecoustics]

I have both pipe in same system type but in different name. This is strange as the second system was split from the first pipe. It should keep the same system name as I just want to add an offset on the pipe. Now I have different system name and I can't change the name to the same. When I add an horizontal pipe, the pipe is even shown as different system type.

I have to say Revit is the most ridicules 3D program I have ever used. I have been using it for 2 years and I've never liked it.

When you edit the system, all the pipes and components are gray. Nothing you can change. So, how to change a pipe's system when you edit a pipe's system?

Remove the entire pipe systems and connect a new one, see steps below:

1. Remove the existing system - roll over your mouse on top of the pipe run and hit "tab" twice, click delete to remove the entire system....your pipe should become white or gray if you are assigning system color within your filter settings....if the pipe runs are deleted then you have done it wrongly, undo and try it again....the idea is to remove the pipes from the system and not to delete the pipes

2. Do this again in the other pipe system......now you have both pipe systems using the "Unassigned" system type

3. Ensure the entire pipe runs are connected together, create a new pipe with the correct system type and connect it to the unassigned systems.....the new system used by the new pipe will now be used for the entire pipe connections.....as one system.....remove the new pipe that you have just created since it is not necessary, it is just a dummy to get your pipes a new system.....reconnect the pipes as required

Thx. I'll remember this as the only way to edit piping system. As the 'edit system' button never works. Autodesk should remove that button from the panel as it make things confusing.

One strange thing is, after I delete the old system per your step one, the pipes don't show in the unassigned area as you said in step 2. See below. But I was able to connect them to another system.

I struggle with the step 3. When I create a new pipe, the system name category in properties is grayed out. Would you help?

Hello,

This new pipe is connected to another pipe or just itself?

You are a genius! Thank you!

AutoDesk needs to fix this glaring issue!!!!

How about simple reassignment?

Why does revit insist on a new unique name? When you click the dropdown on "System Name" on the duct system properties panel you get an error if you select an existing system.

This should be a simple task!!!  Or maybe a click and drag in the "System Browser?

You've just got to realize how Revit thinks about this. If the elements aren't connected, they can't be on the same system. When you connect them, they are on the same system. Instead of trying to change the system name, just connect them to the system that you want them to be on.

Not an Autodesk issue. It works as designed.

How? How in the world is the solution? I am amazed at how often I just have to shake my head in disbelief when I find out that some janky backdoor workaround is just "the way" in Revit. It has it's strengths, but it is definitely the most frustrating program I've ever used.

Why is the solution not?:

1. Select pipe

2. Pick the pipe system you wish it to be from the drop down list

At my company, we call this pipe cancer.

I've always told people to be aware of what they are modeling because making changes to systems after the fact is not always as easy as you would think it would be. Sometimes it is easier to recreate it than it is fix it when it's created incorrectly.

Are you saying that I had to start from scratch my model of a chiller plant in order to change a system type of a single pipe?

[start sarcasm] Yeah, that's what I said. [end sarcasm]

Issued: Single pipe that can't be changed to the desired settings.

Answered: Make a new pipe with the proper settings.

In Revit 2019 I had the same problem. 

I could not change pipe system type in the pipe system editor. I'm sure I was doing something wrong, or out of sequence, but it felt incredibly glitchy to me. 

However, by selecting a single pipe that was part of the system, and changing its system type in the properties browser, I was able to flip the entire connected system to a new one. 

In this case, I accidently changed my hot water to hydronic, and I needed to change it back.

Hello,

When you select a piece of pipe, you can change the system type respecting the same classification.
