How to convert SAT to IGES
- Add your .SAT file - drop it in the box above or click to browse.
- Convert it to .IGES in a few seconds.
- Download your new .IGES file.
What to expect
- IGES was designed for surfaces and wireframes; a SAT solid body may import as disconnected surfaces rather than a closed solid - run a heal or stitch operation in the receiving application.
- If the target system accepts STEP, prefer STEP over IGES - it carries solid B-rep geometry more reliably and is the current international standard.
- Very old IGES readers may not support the IGES 186 solid entity and will see only surfaces; confirm compatibility with the receiving system before delivery.
Frequently asked questions
Is CAD Assistant free for commercial use?
Yes - Open Cascade CAD Assistant is free for both personal and commercial use on Windows, macOS, and Linux with no license fee.
Should I convert SAT to IGES or SAT to STEP?
Choose STEP if the receiving system supports it - it handles solid B-rep geometry better and is the current international standard. Use IGES only when the other party specifically requires it.
Why does my IGES file open with gaps or open shells?
Many exporters output the solid as separate trimmed surfaces that the importer does not stitch automatically. Run a geometry-heal or stitch command in the receiving CAD application to close the model.
Can I convert SAT to IGES on macOS or Linux?
Yes - CAD Assistant runs on macOS and Linux, Fusion 360 is available for macOS, and FreeCAD covers all three platforms including CLI use on Linux.
