At frontline.io, we support a variety of 3D CAD file formats to ensure seamless integration and usability for your digital twin models. Here is an overview of the supported 3D CAD formats and their origins:

3D CAD File Formats and Their Origins

• STEP (STandard for the Exchange of Product model data):
  

  • Origin: Developed by ISO (International Organization for Standardization) as ISO 10303.
    
  • Purpose: A neutral and widely accepted format for exchanging 3D data between different CAD systems, ensuring high interoperability.
    

• IGES (Initial Graphics Exchange Specification)
  

  • Origin: Developed by the U.S. National Institute of Standards and Technology (NIST).
    
  • Purpose: Allows the exchange of 2D and 3D models between different CAD systems, widely used in engineering and manufacturing.
    

• OBJ
  

  • Origin: Created by Wavefront Technologies.
    
  • Purpose: A geometry definition file format commonly used in 3D graphics software, often includes texture mapping.
    

• STL (Stereolithography)

  • Origin: Developed by 3D Systems.
    

  • Purpose: Widely used in 3D printing, it represents the surface geometry of a 3D object without any color or texture information.
    

• FBX (Filmbox)

  • Origin: Initially developed by Kaydara and later acquired by Autodesk.
    

  • Purpose: Popular in animation and gaming industries, it supports complex data like rigging and animations.
    

• 3MF (3D Manufacturing Format)
  

  • Origin: Developed by the 3MF Consortium, including companies like Microsoft, Autodesk, and HP.

  • Purpose: Designed for additive manufacturing, providing a compact and detailed representation of 3D models.
    

• GLTF/GLB (GL Transmission Format)
  

  • Origin: Created by the Khronos Group.

  • Purpose: Optimized for web-based 3D visualization, it’s lightweight and supports PBR (Physically Based Rendering) materials.
    

• DXF/DWG (Drawing Exchange Format/Drawing)
  

  • Origin: Developed by Autodesk.

  • Purpose: Used for both 2D and 3D design data, commonly seen in engineering, construction, and architecture.
    

• 3DXML
  

  • Origin: Developed by Dassault Systèmes for use with CATIA V5 and V6.

  • Purpose: A lightweight 3D format for sharing and visualizing 3D models, compatible with CATIA products.
    

• PXZ
  

  • Origin: Created by PiXYZ Software.

  • Purpose: Designed for optimizing and preparing CAD models for real-time visualization and VR/AR applications.
    

• 3DS
  

  • Origin: Developed by Autodesk for the 3D Studio software.

  • Purpose: A legacy format used for simple 3D geometry and animations.
    

• JT
  

  • Origin: Developed by Siemens PLM Software.

  • Purpose: A compact format for 3D visualization, often used in product lifecycle management (PLM).
    

• PRT (NX-Unigraphics)
  

  • Origin: Developed by Siemens for NX (formerly Unigraphics) CAD software.

  • Purpose: A proprietary format for detailed design and engineering data.
    

• Parasolid
  

  • Origin: Developed by Siemens PLM Software.

  • Purpose: A geometric modeling kernel widely used in CAD applications for high-precision modeling.
    

• Rhino3D (3DM)
  

  • Origin: Developed by Robert McNeel & Associates for Rhino 3D modeling software.

  • Purpose: A versatile format for complex freeform modeling.
    

• SketchUp (SKP)
  

  • Origin: Developed by Trimble Inc. for SketchUp software.

  • Purpose: A format for intuitive 3D modeling, often used in architectural and interior design.
