Convert RFA to SAT

Understanding the RFA and SAT file formats

RFA files are Revit Family files used by Autodesk Revit, a leading Building Information Modeling (BIM) software. These files store parametric 3D models, components, and families used in architectural and engineering projects.

SAT files are ACIS Solid Model files, a neutral 3D CAD format developed by Spatial Corporation. SAT files are widely used for exchanging 3D geometry between different CAD applications, as they store precise solid and surface geometry data.

Why convert RFA to SAT?

Converting RFA to SAT allows you to use Revit family components in other CAD software that supports the ACIS SAT format, such as AutoCAD, SolidWorks, or Rhino. This is essential for interoperability and collaboration across different design platforms.

How to convert RFA to SAT

Direct conversion from RFA to SAT is not natively supported in most software. The recommended workflow involves exporting the RFA content from Revit as a SAT file:

1. Open your RFA file in Autodesk Revit.
2. Load the family into a project or create a new project and place the family instance.
3. Select the family geometry you wish to export.
4. Go to File → Export → CAD Formats → ACIS (SAT).
5. Choose your export settings and save the file with a .sat extension.

This process will export the selected geometry as a SAT file, which can then be imported into other CAD applications.

Best software for RFA to SAT conversion

The most reliable software for this conversion is Autodesk Revit, as it natively supports both RFA files and exporting to the SAT format. For users without Revit, consider using Autodesk Viewer for viewing, but exporting will still require Revit or a compatible plugin.

Tips and considerations

• Only 3D geometry will be exported; parametric data and family parameters are not preserved in SAT files.
• Check the exported SAT file in your target CAD software to ensure geometry integrity.
• For batch conversions, consider scripting within Revit or using third-party plugins.
