Reading Jeremy's The Building Coder blog I was reminded that Ishould share this with you. The ADN group has been successfully releasing add-ins on a monthly bases for a number of Autodesk platforms and this month they are relasing the first Revit add-in. It is a simple but quite helpful productivity tool that lets you renumber rooms.
You can find more details at on Scott's blog post and you can download it from the bottom of this page. You will find that there are also a number of other similar tools from other 3rd party Revit developers each with its own strengths. Check them out and share with us what you think.
