CAD and BIM native format models
CAD and BIM native format models refer to file types that retain all attributes of a model—such as geometry, materials, metadata, and hierarchical structure—within the original software environment. Native formats allow for full editability and interoperability across platforms without data loss. Examples include DWG (AutoCAD), RVT (Revit), and PLN (ArchiCAD).
