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 File 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. Our software employs the Open Cascade framework, providing full support for the most recent IGES specifications.

STP STandardized Exchange of Product File

A file format used for the exchange of 3D data across various computer systems, including CAD, CAM, and CAE, in a standardized format. Some of the benefits and features of STEP files are:

  • Compatibility: STEP is widely supported by many software applications and platforms, making it easy to share and collaborate on 3D models across different domains and industries.
  • Accuracy: STEP preserves the exact shape and dimensions of 3D models, unlike some other mesh formats (SKP, OBJ, or STL) that may introduce errors or distortions during conversion.
  • Materials: STEP file format supports colors per assembly. However, it lacks an alpha component. This means that any transparency effects applied to 3D models will not be visible or preserved in the STEP files.

STEP Files Converter: STEP files can be very large, especially when they contain complex or high-resolution 3D models. One way to reduce the file size is to use Autoconverter software, which can utilize the faceted BREP representation, potentially saving up to one-third of the file size. It uses the Open Cascade framework, ensuring compatibility with the latest STEP standards.
