The Revit add-in writes and compiles C#. The Dynamo extension writes validated Python directly into the graph.
BIBIM drafts a plan before it changes anything.
It pulls model context and writes version-aware code.
BIBIM validates the code, retries when needed, and runs it.
BIBIM is built to execute work, not just suggest snippets.
