Alias Wavefront Object File
A text-based file format that is extensively used for 3D geometry objects across a variety of 3D software programs. Some of the benefits and features of OBJ files are:
- Named Group Objects: OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.
- Surface Materials: The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.
- Geometry Primitives: OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our Autoconverter software, any quad primitives will be simplified into two triangles, as only triangular facets are supported.
- OBJ File Size: Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.
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.
