Convert SAB to IGS

Understanding SAB and IGS file formats

SAB files are proprietary 3D model files used by Autodesk Fusion 360 and AutoCAD. They store 3D solid model data in a binary format, making them suitable for precise engineering and manufacturing workflows. IGS (or IGES) files, on the other hand, are a widely used neutral file format for exchanging 2D and 3D CAD data between different software platforms. IGS files are text-based and support a broad range of geometric and design information, making them ideal for interoperability.

Why convert SAB to IGS?

Converting SAB to IGS is essential when you need to share 3D models with collaborators using different CAD systems. The IGS format ensures compatibility and preserves geometric data across various platforms.

Best software for SAB to IGS conversion

The most reliable way to convert SAB files to IGS is by using Autodesk AutoCAD or Autodesk Fusion 360. Both applications natively support SAB files and offer export options for IGS/IGES.

• Autodesk AutoCAD: Open your SAB file, then use File → Export → Other Formats and select IGES (*.igs) as the output format.
• Autodesk Fusion 360: Import the SAB file, then go to File → Export and choose IGES as the export type.

For users without access to Autodesk products, FreeCAD is a free and open-source alternative that can import SAB files (with the right add-ons) and export to IGS.

Step-by-step conversion process

1. Open your SAB file in AutoCAD or Fusion 360.
2. Go to File → Export or File → Export → Other Formats.
3. Select IGES (*.igs) as the output format.
4. Choose the destination folder and save the file.

Tips for successful conversion

• Check the exported IGS file in a viewer or another CAD program to ensure all geometry is preserved.
• If you encounter issues, try updating your CAD software or using a different export setting.
