What Is a DGN File?

DGN is the native file format for Bentley MicroStation, one of the oldest and most established CAD platforms. MicroStation and its derivative products, OpenRoads, OpenBuildings, OpenRail, are widely used in infrastructure engineering: roads, bridges, rail networks, utilities, and large-scale civil projects. Government bodies, transportation authorities, and national infrastructure agencies frequently mandate MicroStation for major project deliverables.

Opening a DGN file normally requires MicroStation or a Bentley viewer application. A DGN viewer online through ShareCAD removes that dependency, the file is processed via cloud translation and then renders in any browser.

For infrastructure project teams that share DGN drawings with clients, planning bodies, or contractors who do not use MicroStation, ShareCAD provides a direct browser-based view without requiring a Bentley license or viewer installation.

DGN Viewer Use Cases

Infrastructure client reviews

Roads, rail, and utilities consultants share DGN drawings with client organisations, including government bodies, who often do not have MicroStation installed.

Planning and regulatory submissions

Share DGN drawings with planning authorities and regulatory bodies via a browser link. Reviewers inspect the drawing without a Bentley license requirement.

Contractor access to infrastructure drawings

Civil contractors working on infrastructure projects access DGN drawings in their browser on site without specialist CAD software.

Cross-discipline teams

Projects mixing MicroStation and AutoCAD users benefit from a common browser viewer, DGN and DWG files all accessible via the same ShareCAD platform.
