What Is AutoCAD DGN File?

An AutoCAD DGN file is a CAD (Computer-Aided Design) file format that was originally developed by MicroStation, a software application used for designing and drafting in 2D and 3D. AutoCAD, another popular CAD software, added support for the DGN file format to provide interoperability between the two applications.

DGN vs. DWG

AutoCAD uses the DWG (Drawing) file format as its native format, whereas MicroStation uses the DGN (Design) file format. While both formats serve the same purpose of storing design data, there are some differences between them.

The DWG file format is widely used in the architecture, engineering, and construction industries. It is known for its compatibility with various CAD software applications and its ability to store complex design data efficiently. On the other hand, the DGN file format is primarily associated with MicroStation but can also be opened and edited in AutoCAD.

Benefits of Using DGN Files

  • Interoperability: The DGN file format allows users of MicroStation and AutoCAD to exchange design files seamlessly.
  • Layer Support: DGN files preserve layer information, making it easier to organize and manage different elements of a design.
  • Advanced Features: The DGN file format supports advanced features like parametric modeling, rendering, and animation.

How to Open a DGN File in AutoCAD

If you have received a DGN file but only have access to AutoCAD, you can still open and edit it without any issues. Follow these steps:

  1. Method 1: Use the “IMPORT” command in AutoCAD to import the DGN file directly into your drawing. This method allows you to retain the original DGN file as a reference.
  2. Method 2: Convert the DGN file to the DWG format using AutoCAD’s “DGNPURGE” or “DGNEXPORT” command. This method converts the DGN file into a DWG file, which can be edited natively in AutoCAD.

Conclusion

The AutoCAD DGN file format provides a convenient way for users of MicroStation and AutoCAD to collaborate and share design files. With its support for interoperability and advanced features, it offers flexibility in working with CAD data. Whether you need to open a DGN file in AutoCAD or convert it to DWG, you can easily work with this file format without any limitations.
