frontline.io supports a variety of 3D CAD file formats to ensure seamless integration and usability for your digital twin models using Fast Track Pro.

Below is an overview of the supported formats on PC:

Accepted 3D CAD File Formats

  1. 3DM (Rhino3D) – Developed by Robert McNeel & Associates; supports complex freeform modeling used in Rhino 3D.
  2. 3DXML – Dassault Systèmes lightweight 3D format for visualization and sharing within CATIA environments.
  3. 3DPDF – Adobe PDF variant embedding 3D data (typically U3D or PRC) for interactive visualization within PDF viewers.
  4. ASM (Solid Edge Assembly) – Siemens Solid Edge assembly format storing references to multiple part files.
  5. CATPart / CATProduct – Dassault Systèmes CATIA formats for parts and assemblies containing full parametric data.
  6. CGR – CATIA graphics representation format optimized for fast 3D visualization.
  7. DAE (COLLADA) – XML-based interchange format for 3D assets supporting geometry, textures, and animations.
  8. FBX (Filmbox) – Autodesk format supporting complex animation, rigging, and geometry data, common in game pipelines.
  9. GLB / GLTF (GL Transmission Format) – Khronos Group’s lightweight, web-optimized format supporting PBR materials.
  10. IAM / IPT (Autodesk Inventor) – Inventor assembly (IAM) and part (IPT) formats storing full parametric CAD data.
  11. IFC (Industry Foundation Classes) – ISO-certified open standard for exchanging BIM (Building Information Modeling) data.
  12. JT – Siemens PLM lightweight visualization format used in product lifecycle management (PLM).
  13. OBJ – Wavefront geometry definition format supporting vertices, faces, and texture mapping for 3D graphics.
  14. PAR (Solid Edge Part) – Siemens Solid Edge part format storing 3D geometry and design intent.
  15. PLY (Polygon File Format) – Stanford format representing 3D scanned data and polygonal meshes, often with color data.
  16. PRT (NX-Unigraphics) – Siemens NX proprietary part format containing high-precision engineering geometry.
  17. PXZ – PiXYZ Software format for optimizing CAD data for real-time visualization and AR/VR applications.
  18. SLDASM / SLDPRT (SolidWorks) – Dassault Systèmes SolidWorks assembly and part formats containing parametric CAD data.
  19. STEP / STP (ISO 10303) – ISO standard neutral CAD format for exchanging precise 3D product data across platforms.
  20. STL (Stereolithography) – 3D Systems format defining surface geometry for 3D printing and rapid prototyping.
  21. WRL (VRML) – Virtual Reality Modeling Language format for interactive 3D web visualization.
  22. X_B / X_T (Parasolid) – Siemens Parasolid kernel formats for exchanging precise geometric modeling data.
  23. X3D – XML-based successor to VRML for interactive 3D graphics on the web.
Alert
Note: While 3D PDFs are supported, standard (2D) PDFs are not compatible.

Additional Information

If you are using a Mac, Fast Track may be unable to support the full list of file formats. The .FBX is recommended.
​
Please keep in mind that due to the variety of supported formats, some differences may occur when importing files.
These can include:
  1. Material appearance or texture preservation
  2. Model positioning or alignment inside the scene

If you have any questions concerning file formats, please contact frontline.io.
