Yo need to create and start a database transaction before you attempt to modify the model in any way.

Hi,

same reason as here:

"Do you use a Transaction ?

[...] as far as I can see, changes to the Revit DB must be encapsulated in a Transaction, excepting when using the TransactionMode.Automatic attribute for an ExternalCommand."

In your small example, just change the TransactionMode flag to Automatic.
