IGES to OBJ Converter

How IGES to OBJ conversion works

1. Drop your IGES file (.iges or .igs) above.
2. The OpenCASCADE kernel loads on demand and tessellates the CAD geometry into triangles.
3. The mesh is serialized as a Wavefront OBJ file — the format Blender, Maya, Unity and three.js all understand.
4. Preview the result and download the .obj.

Why convert IGES to OBJ?

IGES is one of the oldest CAD exchange formats, still common for legacy parts and surface models. But real-time 3D tools, game engines and renderers want OBJ — a simple, universal mesh format. This tool bridges the two: upload an IGES file, get a clean OBJ mesh back, entirely in your browser.

About the OBJ output

• Plain-text Wavefront OBJ (v vertices + f faces), importable everywhere.
• Units are preserved from the source IGES file; scale in your target app if needed.
• Need STL instead for 3D printing? Use the IGES to STL converter.
