Free Online IGS to OBJ Converter

Use our free-to-use IGS to OBJ CAD to 3D model converter to effortlessly convert your IGS files. Our converter can apply extrusion to your IGS files, which can then be edited in most 3D editing applications. As our IGS to OBJ tool is able to batch convert your files, you can upload a maximum of 20 files at a time.

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your IGS file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted IGS file before this time.

To begin, click the button above and select your IGS CAD files. Once selected, your CAD files will be added to the conversion list. From here, you will be able to set any conversion properties, such as extrusion depth, by clicking the button. When you are ready, click the Convert button to convert your files.

The IGS file format is a Computer Aided Design (CAD) file format originally developed in the 1980s. With the many CAD applications available at the time, all using their own file format, the IGS format was created to be a standard format to exchange data between CAD applications.

All the common features of CAD files can be represented using the IGS format, including basic elements such as lines, curves, text, and other shapes, along with their visual properties such as their color and other metadata.

The IGS format has since been superseded by other, more capable formats, such as STEP; however, IGS files can still be opened with some modern CAD applications. We also have tools for converting IGS files to other CAD and 3D model formats.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.
