Description

IGS is an open file format used within CAD applications as a means of saving data in a format that can be opened and edited in other CAD applications. Its roots can be traced back to the mid-1970s, when it was used by the United States Air Force.

The format itself is a human-readable text-based format and contains data that can represent many different CAD elements, such as points, lines, arcs, and much more. IGS files can be opened with many modern CAD applications, such as FreeCAD.

Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable the storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shapes, and edge information, and it also has support for including color information. As the format is text-based, the files can become rather large, with no built-in compression options available.

OFF Notes

OFF files support per-face color information. If your uploaded model contains color information, our tool will attempt to save this in the OFF file at the end of the conversion process.

Supported Features

  • Mesh geometry
  • Face colors
