Customization has always been a mainstay of design software, especially with the Autodesk products. Customization of Revit for the user/non-programmer is finally here with Dynamo. Dynamo has been in development for some time, but has been gaining momentum among Revit power users. It really opens up the door for users to achieve more functionality through the open-source visual programming extension for Revit. It provides similar opportunities to the Revit user like AutoLisp did for AutoCAD users.
