CAD and BIM native format models
CAD and BIM native format models refer to digital files created and used in their original authoring software environments. These native formats preserve the full integrity of the model, including geometry, materials, metadata, object hierarchy, and parametric rules.
Unlike export formats (such as IFC or STEP), native files allow full editability and maintain software-specific functionality. They are essential for workflows where modifications, collaboration, and version control are required without losing data fidelity.
Common native formats include:
- DWG for AutoCAD and similar 2D/3D CAD platforms
- RVT for Autodesk Revit BIM models
- PLN for Graphisoft ArchiCAD projects
Using native formats supports high-precision design, seamless interoperability within ecosystems, and efficient integration into digital twin and lifecycle management solutions.
