Convert RVT to IGS

Understanding the RVT and IGS file formats

RVT is the proprietary file format used by Autodesk Revit, a leading Building Information Modeling (BIM) software. RVT files store 3D architectural models, including geometry, metadata, and project information. IGS (or IGES, Initial Graphics Exchange Specification) is a neutral file format widely used for exchanging 2D and 3D CAD data between different software platforms. IGS files are especially useful for sharing models with applications that do not natively support Revit files.

Why convert RVT to IGS?

Converting RVT to IGS is essential when you need to collaborate with professionals using different CAD software, or when you want to use Revit models in applications that require the IGES format for manufacturing, analysis, or further design work.

How to convert RVT to IGS

There is no direct export from RVT to IGS within Revit. The process involves exporting the Revit model to an intermediary format, such as DWG or SAT, and then converting that file to IGS using a compatible CAD application.

Step-by-step conversion process

1. Open your project in Autodesk Revit.
2. Go to File → Export → CAD Formats → DWG or File → Export → CAD Formats → ACIS (SAT).
3. Save the exported file to your computer.
4. Open the exported DWG or SAT file in a CAD program that supports IGES export, such as Autodesk AutoCAD or Autodesk Inventor.
5. In the CAD program, use File → Export → IGES or File → Save As → IGES (*.igs) to create the IGS file.

Recommended software for RVT to IGS conversion

• Autodesk Revit (for exporting to DWG or SAT)
• Autodesk AutoCAD (for importing DWG/SAT and exporting to IGS)
• Autodesk Inventor (for advanced 3D model conversion)
• FreeCAD (open-source alternative for DWG/SAT to IGS conversion)

Tips for successful conversion

• Check the integrity of your model before exporting from Revit to avoid missing geometry.
• Use the highest compatibility settings when exporting to DWG or SAT.
• After conversion, review the IGS file in a viewer to ensure all elements are correctly transferred.
