Convert IGES to OFF: The Key Insights

IGES to OFF: Resources

Below, you'll discover a compendium of resources dedicated to the interoperability and exchange of IGES and OFF file formats. These will aid in the smooth conversion from IGES to OFF files.


The IGES (Initial Graphics Exchange Specification) file format serves as the foundational format for data exchange between various systems, including CAD, CAM, and CAE. Since IGES geometry data is stored in a text format, exporting triangular meshes with thousands or millions of faces using our Autoconverter software may result in larger file sizes. It’s important to note that while the IGES format supports color per assembly, it does not include an alpha component. Consequently, any transparency settings will be lost when saving your stunning 3D design in the IGES format.


The OFF (Object File Format) is a file extension used for ASCII text files that contain geometric data of 3D polygonal objects. The OFF file format supports standard 3D triangles, quads, and other generic polygonal shapes. Our Autoconverter software serves as a primary OFF file converter, allowing you to easily convert OFF files into various other mesh file formats. Alternatively, Autoshaper, our other OFF file converter, enables you to transform your OFF files into smooth NURBS shapes. However, it’s worth noting that while the OFF file format is versatile, it does not support the conversion of materials, textures, or group names from more sophisticated 3D file formats.
