How to convert IGES to DAE
- Add your .IGES file - drop it in the box above or click to browse.
- Convert it to .DAE in a few seconds.
- Download your new .DAE file.
What to expect
- IGES surfaces are tessellated into a triangle mesh; curved geometry becomes faceted, and mesh density determines how smooth it looks.
- Exact analytic geometry (NURBS, B-rep) and CAD metadata are not preserved; the output is display/interchange mesh geometry.
- An IGES source carries no textures, so the resulting DAE is untextured geometry.
Frequently asked questions
Does the output keep exact CAD geometry?
No. IGES stores precise surfaces and curves, but DAE (COLLADA) is a mesh and scene format, so the geometry is tessellated into triangles. Smooth surfaces become faceted approximations.
Why convert IGES to DAE?
DAE is a widely supported interchange format for 3D scenes, useful for bringing CAD shapes into tools like Blender or for further conversion to glTF for web and AR use.
Where does a DAE open?
Free in Blender on any platform, in macOS Preview, and in many 3D and game tools that read COLLADA XML.
What is lost?
Parametric and exact surface definitions, CAD feature data, and tolerances are not retained. DAE carries only the meshed result, plus optional colour and scene structure.
