Autodesk Dynamo

Free Design the Building

Open-source, node-based visual programming environment for computational design and BIM automation, embedded in Revit and Civil 3D (also standalone as Dynamo Sandbox); build parametric graphs with Python and Zero-Touch C# nodes to generate geometry, bulk-edit BIM parameters, and automate repetitive modeling tasks.
