upgrade to revit 2024: changing air-flow (air terminals) causes fatal error

[dirk_h]

Hey,

Recently my Revit MEP-model (2020) was upgraded to Revit 2024. All the air-flow-values on the air terminals were unwanted changed to "0". When I try to change the flow values (top left), Revit experierences a fatal error and cannot continue. Any idea what is causing this?  

Thanks in advance!

Don't know but some things you might try:

• activate Show Disconnects for ducts and check that everything is still connected properly. Upgrading sometimes causes systems to break.
• activate Check Duct Systems and see if there any warnings for the systems.
• try substituting a different grille/diffuser family and see if the problem persists for the substitute terminal type.

Also same here.

The solution to this problem is, as I discovered after my answer above, to apply updates to the 2024 version.

The current version is 2024.3.1 and in Help > About it should show the build version as
