What is a DGN file?

A DGN file is a 2D/3D drawing created by various construction CAD software, such as MicroStation and Intergraph Interactive Graphics Design System. It may be saved in one of two formats, either the Intergraph Standard File Format (ISFF) or the newer V8 DGN standard. DGN files are typically used to save designs for construction projects for highways, bridges, and buildings.

More Information

DGN files can be opened by Bentley Systems MicroStation and the free Bentley View program. The DGN format is also supported by several other third-party programs, such as Autodesk AutoCAD and IMSI TurboCAD. DGN files can be converted to the more universal .DWG format by AutoCAD LDT.

NOTE: The DGN extension is short for "design."
