DWG (AutoCAD Drawing)

DWG is AutoCAD’s native binary drawing format. It stores 2D drafting and 3D geometry together with layers, blocks, dimensions and text. The format is proprietary and changes with AutoCAD releases, which is why many programs cannot open it.

Used by: Architects, civil and mechanical engineers, and anyone receiving drawings exported from AutoCAD, BricsCAD or DraftSight.
