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The IGS format has since been superseded by other, more capable formats, such as STEP; however, IGS files can still be opened with some modern CAD applications.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.

IGS Converter Capabilities

Currently, our IGS converter can only convert from IGS files, our developers are working to allow converting to IGS files in future versions of our tools.
