Open DGN files in your browser
View DGN files (V7 and V8) in your browser without MicroStation (β). Handy for checking legacy civil-engineering, plant, and rail drawings.
Can't open a DGN file? Common causes and fixes
No MicroStation license, and nothing else opens the DGN
If it's a V7 (2D) or V8 DGN, just drop it on this page to view it.
It's a V7 3D design, outside the beta's coverage
V7 3D is not supported yet. If a file fails to open, submitting it helps us support it sooner.
Convert it while you're here
A displayed DGN file can be converted straight to DXF, PDF, SVG, or PNG — and the loss report shows exactly what survived the conversion.
FAQ
DGN viewer — frequently asked questions
Are V8 DGN files supported?
Yes — both V7 (2D) and V8 are supported. Multi-model V8 files show their first model, and 3D models are projected onto the XY plane; any projection or skip is disclosed in the loss report.
Can I convert DGN to DWG or DXF?
DGN to DXF conversion is available in beta; DXF opens in AutoCAD and most other CAD software. Direct DWG output is on the roadmap.
