Modifying is forbidden because the document has no open transaction. The document has no open transaction. In Revit Document.

Since you tagged this as revitpythonshell:

try:
    transaction = Transaction(doc, 'a name for your transaction)
    transaction.Start()
    do_stuff_that_needs_to_modify_document()
    transaction.Commit()
except:
    transaction.Rollback()
    throw_hands_up_in_the_air_and_cry_in_frustration()

You have 2 options:

  1. change the TransactionMode to Automatic at the class attribute

    [Transaction(TransactionMode.Automatic)]

  2. open a transaction within your command

    Transaction tr = new Transaction(commandData.Application.ActiveUIDocument.Document); tr.Start("Command name here");

    // your code

    tr.Commit();

  • Remember to always put transactions in a using block, as demonstrated here: https://boostyourbim.wordpress.com/2012/12/04/use-a-using-block-with-transactions/ & http://thebuildingcoder.typepad.com/blog/2012/04/scope-and-dispose-transactions.html – Colin Stark Jul 15 '15 at 18:28
