RvtIO

RvtIO is a .NET library and command line tool that reads Autodesk Revit projects (.rvt) and families (.rfa) directly from disk, without Revit or the Revit API, and exports IFC and JSON.

• Reads elements, parameters, geometry, file metadata and project information.
• Queries elements through FilteredElementCollector.
• Exports IFC2X3 coordination view, with optional Revit parameters as property sets.
• Writes compact JSON or a full JSON dump with every parameter and geometry.
• Returns the triangle meshes of the model elements, with one shared mesh per family symbol for repeated instances (ElementMeshes).

The library targets .NET 8 and .NET 10, uses managed code only, and supports Windows, Linux and macOS.
