Hi Frederick, the delay is from generating undo records for object style assignments on every name change.

You can avoid that from happening if you bracket your style modification loop with moi.geometryDatabase.styleEditorOpened(); / moi.geometryDatabase.styleEditorClosed(); like in the attached version.

With that in place it will only generate the undo record one time and should be much faster.

Hi Michael,

I was going to ask if there was a way to disable the collection of undo information - and it turns out there is.

Thanks.
