Preferences: "Isolate Selected Geometry" visual setting not saving

Hello everyone,

I’ve noticed that over the last few months, the “Isolate Selected Geometry” setting in Dynamo’s Preferences no longer seems to persist after closing Revit.

I’ve encountered this issue in multiple versions, including:

  • Dynamo 3.7 on Revit 2026
  • Dynamo 2.16 on Revit 2023

Has anyone else experienced this issue, or is there a way to make the setting persist between sessions? Thanks!

Toggle the setting and then check your Dynamo preferences file. A lot of people and companies do odd things to that settings file which can alter how the setting gets picked up.

Do you mean “DynamoSettings.xml” located here?

%APPDATA%\Dynamo\Dynamo Revit\-----version----\DynamoSettings.xml

I can’t seem to find the option..

I tried copying the xml, change the option, close dynamo and compare the two files but they are identical.

So the tags aren’t always that transparent - they can sometimes have VERY different settings. That said I just reproduced in 3.0 to see if I could find the flag, and I don’t have any environment manipulations on my system at the moment (long sad story for a different date and venue).

I’ll see if the team can have a look for you. :slight_smile:

Did the littlest bit more digging and tried forcing a value. Looks like the preferences initializer doesn’t work anymore, likely got hit during the 2.13 update but I can’t run builds that old to confirm at the moment (same sad story as above).

In the meantime you can hopefully make do with ctrl+i which is the keyboard shortcut to toggle the feature and still works in 4.2.

thanks @jacob.small for your kindness!
