Convert RFA to IGS

Understanding the rfa and igs file formats

RFA files are Revit Family files used by Autodesk Revit, a leading Building Information Modeling (BIM) software. These files store 3D models, parameters, and metadata for architectural components such as doors, windows, or furniture.

IGS (or IGES) files are a widely used neutral CAD file format for exchanging 2D and 3D design data between different CAD systems. The IGES format is ideal for sharing models across various engineering and manufacturing platforms.

Why convert rfa to igs?

Converting an RFA file to IGS format allows you to use Revit models in other CAD or CAM software that does not natively support Revit files. This is essential for collaboration between architects, engineers, and manufacturers using different design tools.

How to convert rfa to igs

Direct conversion from RFA to IGS is not natively supported in most software. The typical workflow involves exporting the RFA file to an intermediate format (such as DWG or SAT), then converting that file to IGES.

Step-by-step conversion process

1. Open your RFA file in Autodesk Revit.
2. Load the family into a project and place the component in a view.
3. Go to File → Export → CAD Formats → DWG to export the model as a DWG file.
4. Open the exported DWG file in Autodesk AutoCAD or Autodesk Inventor.
5. In AutoCAD, use File → Export → Other Formats → IGES (*.igs) to save the file as an IGES file.

Best software for rfa to igs conversion

• Autodesk Revit – for exporting RFA to DWG or SAT.
• Autodesk AutoCAD or Autodesk Inventor – for converting DWG/SAT to IGES.
• FreeCAD – an open-source alternative that can import DWG (with plugins) and export IGES.

Tips and considerations

• Some geometry or parameters may not transfer perfectly; always check the IGES file after conversion.
• For complex families, consider simplifying geometry before export to ensure compatibility.
• Use the latest versions of software for best compatibility and export options.
