just wanted to let everybody know that we've posted an updated version of our Content Creation Tutorial on our website, you can find them at www.autodesk.com/revitmep-documentation
They are towards the bootm of the page. You will find that we have added some material as well as re-formatted the content like a standard tutorial.
Any comments are welcome.
Cheers,
