Legacy compatibility
Some CAM tools and older systems only ingest IGES — convert CATIA and import smoothly.
CATIA to IGES中文
CATIA to IGES Converter Online
Convert CATIA (.CATPart / .CATProduct) into IGES (.igs / .iges) for legacy CAD/CAM systems and surface exchange workflows. Done online in WO3D — no CATIA license required.
Surface exchange
IGES remains useful for surface and wireframe handoff in specific pipelines.
No CATIA license
No Dassault software needed — upload CATPart / CATProduct in the browser.
When to use it
When a downstream CAM tool, supplier or client specification only accepts IGES, convert CATIA to IGES to interoperate.
If there is no hard IGES requirement, STEP usually offers better solid and assembly support — convert CATIA to STEP instead.
IGES trade-offs
IGES is broadly compatible but handles solids and assemblies less robustly than STEP.
Use it when the recipient specifically requires IGES to avoid unnecessary geometry loss.
Prefer STEP otherwise
For most modern cross-CAD collaboration, CATIA to STEP is the safer neutral path.
Pick the neutral format the recipient asks for.
