OFF to IGES Conversion

The list below offers valuable resources, featuring comprehensive guides and expert tips for converting OFF files to IGES format using our converters. Start exploring now to facilitate your OFF files conversion later.

OFF Object File Format

A simple and flexible file format for 3D polygonal objects. It is a versatile tool for storing and transferring 3D geometric data. It has the following features:

  • ASCII Text Files: : The OFF files are text-based and use a simple syntax to store geometric data of 3D objects. The files can be easily edited and viewed with any text editor or viewer.
  • Polygonal Shapes: The OFF files can store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.
  • OFF Converters: Autoconverter is our primary OFF file converter that can convert OFF files into other mesh file formats, such as STL, SKP, OBJ, PLY, etc. Autoshaper is another OFF file converter that can convert OFF files into smooth NURBS shapes, and save them into BREP, STEP, IGES, etc.
  • Limitations: The OFF files do not support the conversion of materials, textures, or group names from more sophisticated 3D file formats. These attributes are not stored in the OFF files and are lost during the conversion process.

IGS Initial Graphics Exchange File

A file format widely used in the fields of CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering), as it enables to transfer of 3D models and designs across different platforms and applications. It has the following features:

  • Text Format: IGES uses a text format to store geometry data, which means it can be easily readable and editable. However, this also means that IGES files can become very large when exporting complex shapes or meshes with many faces.
  • Color Support: The IGES format supports color per assembly, enhancing the visual appeal of your 3D designs.
  • Transparency Settings: One limitation of the IGES format is the absence of an alpha component. This means that any transparency settings in your 3D design will be lost when saved in the IGES format.
  • IGES Converters: Autoconverter supports IGES format for reading and writing, however it can only work with triangulated mesh geometry. If you need to preserve smooth IGES surfaces you should use Autoshaper instead.
