Animation pipelines
FBX is the bridge into 3ds Max, Maya and Motionbuilder for IGES assets.

Convert IGES (.igs / .iges) into FBX for animation and real-time pipelines — 3ds Max, Maya, Unity and Unreal Engine. Done online in WO3D — no install required.
FBX is the bridge into 3ds Max, Maya and Motionbuilder for IGES assets.
Import IGES geometry into Unity and Unreal for product visualization.
No CAD software needed — upload IGES in the browser and get FBX out.
When legacy IGES data needs to enter a visualization, VFX or game-engine pipeline, FBX is the most expected interchange format.
For pure web delivery use glTF / GLB; choose FBX when your toolchain is built around Max, Maya, Unity or Unreal.
IGES surfaces are tessellated to meshes; exact CAD data is not preserved.
Keep a STEP export if editable engineering geometry is still needed.
FBX is dominant in DCC and game engines; glTF is the open web/real-time standard.
Pick the one your downstream tool prefers.
