What Is a DGN File AutoCAD?

If you work with AutoCAD, you may have come across the term “DGN file.” But what exactly is a DGN file and how does it relate to AutoCAD? In this article, we’ll explore the ins and outs of DGN files in the context of AutoCAD.

The Basics

A DGN file, short for “design,” is a proprietary CAD file format primarily associated with Bentley Systems’ MicroStation software. However, AutoCAD also has the capability to read and work with DGN files.

Key Features:

  • Cross-Platform Compatibility: One of the key advantages of DGN files is their cross-platform compatibility. While AutoCAD primarily uses DWG files as its native format, it can also import and export DGN files.
  • Geospatial Data Support: DGN files have built-in support for geospatial data, making them particularly useful for projects that involve mapping or surveying.
  • Layer Management: Like DWG files, DGN files also support layers, allowing for better organization and management of complex CAD drawings.

Differences from DWG

While both DGN and DWG are CAD file formats commonly used in the industry, there are some notable differences between them. Here are a few key distinctions:

  • DWG (Drawing) is Autodesk’s native file format for AutoCAD and other Autodesk software. On the other hand, DGN (Design) is Bentley Systems’ proprietary format primarily used with MicroStation.
  • DWG files are generally smaller in size compared to DGN files, making them easier to share and transfer.
  • DWG files have better compatibility with third-party software and plugins, while DGN files may require additional conversion steps in some cases.

Working with DGN Files in AutoCAD

If you need to open or import a DGN file in AutoCAD, the process is relatively straightforward. Here’s how:

  1. Launch AutoCAD and go to the “File” menu.
  2. Select “Open” or use the “Ctrl+O” keyboard shortcut.
  3. In the file dialog box, change the file type to “DGN (*.dgn)” using the drop-down menu.
  4. Navigate to the location of your DGN file and select it.
  5. Click “Open” to import the DGN file into your AutoCAD workspace.

Note: It’s important to remember that while AutoCAD can read and work with DGN files, there may be some limitations or compatibility issues depending on the complexity of the original DGN file and any specific features or data it contains.

In Conclusion

DGN files are a CAD file format primarily associated with Bentley Systems’ MicroStation software but can also be read and worked with in AutoCAD. They offer cross-platform compatibility, geospatial data support, and layer management capabilities. While DWG remains Autodesk’s native format for AutoCAD, understanding how to work with DGN files can be valuable when collaborating with colleagues or clients who use MicroStation or when dealing with projects that involve geospatial data.
