How to convert DXF to IGS
- Add your .DXF file - drop it in the box above or click to browse.
- Convert it to .IGS in a few seconds.
- Download your new .IGS file.
What to expect
- IGS is simply an IGES file; the result is the same neutral CAD geometry format.
- Annotations, dimensions, hatching, and layer data from the DXF are not represented in IGS and are generally dropped.
- Converting between two geometry standards can introduce minor approximations in curves or surfaces; a 2D DXF becomes wireframe/curve geometry rather than a solid.
Frequently asked questions
Is IGS the same thing as IGES?
Yes.
IGS is just the common three-letter spelling of an IGES file - the same vendor-neutral ASCII CAD exchange format (ISO-era standard). The conversion writes DXF geometry into that IGES structure.Why convert DXF to IGS?
IGES/IGS is supported across many CAD programs, so converting helps carry geometry from AutoCAD's DXF exchange format into a neutral form that a broad range of CAD tools can import as curves and surfaces.
Which programs open an IGS file?
IGS files open free in FreeCAD, Open Cascade CAD Assistant, and the Autodesk Viewer online, as well as most commercial CAD packages. The file is plain ASCII geometry data.
Can I 3D print the IGS directly?
No - IGS holds CAD geometry, not a printable mesh, so you would convert it to STL first for 3D printing. On its own it is intended for exchanging models between CAD programs.
