Dynamo

Open-source visual programming for computational design automation

Open-source graphical programming platform for AEC professionals that enables computational design workflows without coding knowledge. Users create automation scripts by connecting visual nodes in a canvas-based interface. Available as a free add-in for Revit and Civil 3D, plus standalone Dynamo Sandbox. Supports C# custom node development and integrates with 100+ community packages.

Market LeaderOpen Source (Apache License 2.0)
Founded 2012 · Millions of Revit users worldwide (integrated by default); 32K+ GitHub commits; 1000+ community packages

WHY IT EXISTS

Why This Tool Exists

The Problem

AEC professionals need to automate repetitive design tasks (parameter updates, drawing generation, data transformation) but lack coding expertise. Manual workflows consume 3-5 hours per project phase for tasks like renumbering elements, creating schedules, or coordinating between design tools. Building custom tools requires deep API knowledge unavailable to most design teams.

The Solution

Visual node-based programming platform where users drag-and-drop nodes representing functions and wire them together. No coding required for common tasks. Includes nodes for Revit geometry, Civil 3D corridors, file I/O, and data manipulation. Community packages extend functionality. Zero-Touch C# import allows developers to add custom libraries without coding custom nodes.

Exactly what this tool uses and how

Input
What it needs
Required:Visual node definitions, Input data sources (files, parameters, geometry)
Optional:Custom C# libraries (Zero-Touch imports), External data connections, User scripts
Formats:DYN (Dynamo script format), RVT/DWG (geometry imports), CSV/Excel (data imports), C# DLL libraries
Output
What you get
