How to convert FBX to IGES

  1. Add your .FBX file - drop it in the box above or click to browse.
  2. Convert it to .IGES in a few seconds.
  3. Download your new .IGES file.

What to expect

  • FBX is mesh/scene data; the IGES result is faceted geometry derived from that mesh, not clean parametric CAD solids.
  • Animation, rigs, cameras, lights, materials, and textures are not represented in IGES and are lost.
  • Dense meshes can produce large, heavy IGES geometry that is awkward to edit in CAD.

Frequently asked questions

Does FBX geometry become a true CAD solid in IGES?
Not as smooth parametric solids. FBX carries polygon mesh geometry, and exporting to IGES yields surfaces/geometry derived from that mesh rather than the exact B-rep solids a CAD system authors natively. The shape transfers, but as tessellated geometry.
Why convert FBX to IGES?
FBX is a 3D scene interchange format from the animation and games world, while IGES is a neutral CAD standard. Converting moves the model toward CAD tools that read IGES rather than mesh-scene formats.
Where can I open the IGES output?
Neutral CAD viewers and programs such as FreeCAD and Open Cascade CAD Assistant read IGES, and it is broadly accepted across CAD applications as a vendor-neutral exchange format.
What does not carry across from FBX?
FBX-specific content - animation, rigs, cameras, lights, and materials/textures - has no equivalent in IGES and is dropped. Only geometry is meaningful in the IGES result.
