Dynamo

Short answer

Autodesk's visual programming environment, used inside Revit and Civil 3D to automate model and design tasks with node graphs.

Dynamo is a visual scripting environment that lets users build automation by wiring nodes together instead of writing text code. It ships built into Revit (and as a separate add-in for Civil 3D), and it can call most of the host application's API plus arbitrary Python and DesignScript. Dynamo files are .dyn (graphs) and .dyf (custom nodes). Dynamo is the dominant automation tool for Revit users who don't want to write C#.
