Arrayed air terminals not attached to duct

[Anonymous]

Hi, I am learning array tool by working on revit built-in mechanical template.

The interesting thing is:

I modeled a piece of duct and attached an air terminal on it, then I arrayed it. The arrayed air terminals all attached to the duct.

However, when I did the same thing on 2nd level, I didn't work. All arrayed air terminals not attached to the duct.

Someone knows why?

Hello @Anonymous,

I think you found a BUG.

When I did the same as you did with an OOTB Revit Air terminal I experienced the same problem.

I will create a video that shows the problem.

Is seems that the array function only works when the duct is on the first Level (Reference Level = Level 0)

You can fix it by setting the Reference Level parameter for the Duct to Level 1 and then Array the Air Terminals.

After that set the Reference Level back to the original Level.

I will report this to Autodesk.

Hello @Anonymous,

In the video below you see that I reproduced your problem.

Thank you very much @robert.klempau. Even though I still couldn't see your video.

But I am sure I understand what you mean. In a project I am doing, since the original "1st level" has been removed by my colleague, I even couldn't array air terminals to attach to duct at any level... Looks like, manually attaching is the only solution at the moment. Hope, the autodesk team will solve that in next version.

Thanks again rklempau. You helped me a lot these days and always provide the accurate answer I desire!

Hello @Anonymous,

I just received a mail from Autodesk about the issue.

This incident is being investigated for a possible cause and resolution.

Please see the AKN article they placed:

REVIT – Arrayed air terminal not attached to ducts when not working on level 1.

My video is there too
