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.
  • 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.


IFC Industrial Foundation Classes File

A file format that is widely used in the AEC (Architecture Engineering Construction) industry. It is supported by many software applications, such as Revit from Autodesk or SmartPlant 3D by Intergraph. IFC can store various types of information related to AEC projects, such as:

  • Geometry: IFC can represent the shape and size of 3D models, using different types of entities such as solids, surfaces, curves, or points.
  • Units: IFC can specify the measurement units for each 3D model, such as meters, inches, degrees, or radians.
  • Materials: IFC can define the color and transparency of each geometry component, using values from 0 to 1 for red, green, blue, and alpha channels.
  • Instances: IFC can reuse the same geometry component multiple times, by creating mapped items that refer to the original shape definition. This can save storage space and improve performance.
  • Structure: IFC can organize the 3D models into a hierarchical structure, using names and identifiers for each component. This can help to manage complex projects and facilitate collaboration.
  • BIM: IFC can include generic BIM (Building Information Modeling) data, such as properties, attributes, relationships, or constraints for each 3D model. This can enhance the functionality and interoperability of the file format.

IFC File Converters: Autoconverter and Automesher Application are compatible with IFC, and you can use them to import and export IFC models. You can also modify the custom properties of the IFC geometries, and convert them to other 3D file formats. However, please note that some features of IFC may not be supported by other file formats, and may be lost during the conversion.
