Convert RVT to IGES

Understanding RVT and IGES 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. IGES (Initial Graphics Exchange Specification) is a neutral file format widely used for exchanging 2D and 3D CAD data between different software platforms. IGES files, with the .igs or .iges extension, are especially popular in engineering and manufacturing workflows.

Why convert RVT to IGES?

Converting RVT to IGES enables interoperability between BIM and CAD environments. This is essential when sharing architectural models with engineers or manufacturers who use CAD software that does not natively support RVT files. IGES provides a standardized way to transfer geometry and design data for further processing or fabrication.

How to convert RVT to IGES

Direct conversion from RVT to IGES is not natively supported in Revit. The process typically involves exporting the RVT model to an intermediary format, such as DWG or STEP, and then converting that file to IGES. Here’s a step-by-step method using Autodesk Revit and Autodesk Inventor:

1. Open your project in Autodesk Revit.
2. Go to File → Export → CAD Formats → DWG to export your model as a DWG file.
3. Open the exported DWG file in Autodesk Inventor or another CAD software that supports DWG import and IGES export.
4. In Inventor, use File → Export → CAD Format → IGES (*.igs) to save your model as an IGES file.

Recommended software for RVT to IGES conversion

• Autodesk Revit – for exporting RVT to DWG.
• Autodesk Inventor – for importing DWG and exporting to IGES.
• Autodesk Navisworks – can also be used for model aggregation and export.
• AnyCAD Exchange or Okino PolyTrans – third-party tools that support advanced file conversions.

Tips for successful conversion

• Check geometry integrity after each conversion step to ensure no data loss.
• Clean up your Revit model before export to avoid unnecessary elements in the IGES file.
• Use the latest versions of software for best compatibility and feature support.
