How to Open DGN Files in AutoCAD 2019?

Understanding DGN Files and AutoCAD

DGN files are design files commonly associated with applications like MicroStation, utilized for both 2D and 3D drawings. AutoCAD, a popular design software, does not directly open DGN files; instead, it facilitates their conversion into a more compatible format, specifically DWG files.

Step-by-Step Guide to Open DGN Files in AutoCAD 2025

Step 1: Prepare the DGN File

Before initiating the process, ensure that the DGN file you wish to open is accessible on your computer. The file should be within a limit of 100 MB to ensure smooth processing.

Step 2: Launch AutoCAD

Open AutoCAD 2025 on your computer. Allow the program to load completely before proceeding to the next steps.

Step 3: Access the Import Feature

  1. Navigate to the top menu and locate the Application Menu (usually found in the upper-left corner).
  2. From the dropdown, select Import and then choose Import DGN from the submenu. Alternatively, you can type ImportDGN directly into the command line.

Step 4: Select the DGN File

A dialog box will appear prompting you to navigate your computer’s files:

  1. Click on Browse to locate the DGN file.
  2. Select the desired DGN file and click Open to load it into AutoCAD.

Step 5: Configure Import Settings

  1. Upon loading the DGN file, the Import DGN Settings dialog box will pop up.
  2. Here, you can choose the desired design model from a list provided, which contains options tailored for your project needs.
  3. Adjust the import options as necessary, focusing on aspects like layers and styles. Confirm your choices by clicking OK.

Step 6: Insert the File

Once the import settings are established, AutoCAD will process the DGN file. You may need to adjust the placement or scale of the imported file within your workspace.

Step 7: Save the Project

After making necessary adjustments, it’s crucial to save your project. Save it in DWG format to retain the modifications you have made.

Converting DGN to DWG Directly in AutoCAD

If preferred, you can also directly convert DGN files to DWG format:

  1. Open the DGN file as detailed above.
  2. Once imported, immediately use the SAVE AS option in the Application Menu.
  3. Select DWG format as your save option and name the file accordingly.
  4. Click Save to finalize the conversion.

Frequently Asked Questions

Can I open DGN files in earlier versions of AutoCAD?

Yes, while the process may slightly differ, earlier versions also support DGN file import with similar steps.

Are there any other software options to view DGN files?

You can also use applications like MicroStation or free tools like DWG TrueView to open DGN files without AutoCAD.

Will all features of the DGN file be preserved when importing into AutoCAD?

Some features may not transfer perfectly, as there are differences in how AutoCAD and DGN-based programs handle certain elements. It is advisable to review the imported content for accuracy.
