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.
- 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.
OFF File 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.
3D Manufacturing File
An open-source XML file format that was created by the 3MF Consortium, a group of companies and organizations involved in the 3D printing industry. Unlike the older STL format, which only stores the geometry of 3D models, 3MF can also store additional information, such as:
- Color: 3MF can define the color of each triangle in a 3D model, allowing for more realistic and detailed prints.
- Transparency: 3MF can specify the opacity of each triangle or vertex in a 3D model, enabling the creation of transparent or translucent objects.
- Texture: 3MF can associate a 2D image with a 3D model, and map the image coordinates to the model coordinates, resulting in textured prints.
- Metadata: 3MF can include custom data such as author, title, description, or license for each 3D model, facilitating the sharing and management of 3D files.
3MF File Converters: Our products, Autoconverter and Automesher Application, are compatible with 3MF. To import and export 3MF files they utilize the official lib3mf library. However, there is one limitation that you should be aware of: 3MF does not support group hierarchies, which are used to organize 3D models into hierarchical subgroups. Therefore, if you have a 3D model that contains group hierarchies, you will lose them when you convert it to 3MF.
