MicroStation Design Format | Bentley Systems | CAD Files |
A .DGN file is a MicroStation Design graphic file created with Bentley Systems MicroStation. This vector-based graphics format is used in CAD (Computer Aided Design) to store drawings made in MicroStation. When saved, a .DGN file contains a design's layout, text, hatches, images, objects, cell as well as other elements of the drawing.
File Information
.DGN files can be used for both 2D and 3D designs and may also include information about the components used in building the design as well as any design constraints. This type of file can be exported into various formats including .JPG, .DWG, and .DXF, making it possible to transfer data between different CAD programs. The file is also backward compatible and can be opened by even older versions of MicroStation, allowing users to modify older designs without the need to redraw them from scratch.
Applications
MicroStation
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DGN) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DGN extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DGN file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DGN extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DGN extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DGN file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DGN file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DGN file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DGN file) will be extended to the maximum.
It is also good to check
- if the .DGN file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
