Pyrevit [exclusive] -

is an open-source, third-party add-in for Autodesk Revit that allows users to create, manage, and run scripts written in Python. It serves as a framework that dramatically lowers the barrier to Revit automation, enabling architects, engineers, and BIM coordinators to streamline repetitive tasks without needing to compile traditional C# plugins. The tool has become a cornerstone of many BIM workflows due to its flexibility, community-driven library of tools, and zero-cost entry.

Every Python script needs a way to talk to you. PyRevit provides an HTML-based output window. pyrevit
