About DGN files
A .DGN file is the native 2D/3D design format used by MicroStation and other CAD software from Bentley Systems. While it is the industry standard for large-scale civil engineering projects - such as bridges, highways, and plant design - it presents significant interoperability hurdles for users outside the Bentley ecosystem. The format is proprietary, meaning viewing these files typically requires installing heavy, expensive software like MicroStation or specialized viewers. Furthermore, users often encounter version conflicts between the legacy V7 format (limited to 63 levels) and the modern V8 format, which can disrupt data integrity during imports. To collaborate effectively with architects using AutoCAD, users frequently need to convert .DGN to DWG or DXF. For reviewing designs without specialized CAD tools, converting to PDF is the most accessible solution for sharing, while OBJ or FBX conversions facilitate 3D visualization in rendering software.
Convert.Guru analyzes your DGN file, detects the exact format, and lets you read the text inside.
If you want to convert DGN file to DWG, PDF, DXF, SHP, KMZ, JPG, RVT, RFA, SKP, 3DM, STEP or IGES, you can use MicroStation or similar software from the "Infrastructure CAD Design" category. In the File menu, look for Save As… or Export….
To convert SLDASM, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART, DXF or X_T files to DGN, try MicroStation or another comparable tool in the "Infrastructure CAD Design" category.
The DGN Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DGN converter.
