What is DGN file?

DGN (short for ”design”) is a file format used by Computer Aided Design (CAD) software used by Bentley Systems MicroStation. DGN files store 2D/3D project data. The format is typically used in architectural and contsruction-related projects, such as road, bridge, powerplant or shipyard development.

Two versions of DGN format

The older version was based on Intergraph Standard File Formats (ISFF). Said version is sometimes called V7 DGN or Intergraph DGN. The newer version, introduced by Bentley Systems in 2000, no longer conforms to the ISFF specification and was designated as V8 DGN.

Programs that support DGN file

We hope we helped you solve the problem with the DGN file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the DGN file (apart from the lack of the proper application installed).

First - the DGN file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the DGN file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the DGN file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the DGN file has not been completed and it cannot be opened properly).
