Convert DFT to DGN

Understanding dft and dgn file formats

DFT files are typically associated with Siemens NX (formerly Unigraphics), where they represent drafting documents containing 2D engineering drawings. These files are used for technical documentation and are integral to the CAD workflow in Siemens NX environments.

DGN files are the native format for Bentley MicroStation and are widely used in the architecture, engineering, and construction (AEC) industries. DGN files store 2D/3D vector graphics and are a standard for infrastructure and civil engineering projects.

Why convert dft to dgn?

Converting DFT to DGN is often necessary when collaborating between teams using Siemens NX and Bentley MicroStation, or when integrating NX-generated drawings into larger infrastructure projects managed in DGN format.

How to convert dft to dgn

There is no direct one-step converter for DFT to DGN due to the proprietary nature of both formats. However, you can use an intermediate format such as DWG or DXF to bridge the conversion:

1. Open your DFT file in Siemens NX.
2. Export the drawing to DWG or DXF: File → Export → AutoCAD DXF/DWG.
3. Open the exported DWG/DXF file in Bentley MicroStation.
4. Save or export the file as DGN: File → Save As → DGN.

Best software for dft to dgn conversion

• Siemens NX: For opening and exporting DFT files to DWG/DXF.
• Bentley MicroStation: For importing DWG/DXF and saving as DGN.

There are no reliable online converters for this workflow due to the proprietary nature of DFT files. Using the original CAD applications ensures the best fidelity and compatibility.

Tips for successful conversion

• Check layer and object compatibility after conversion, as some elements may not translate perfectly.
• Review the final DGN file in MicroStation to ensure all annotations, dimensions, and graphics are intact.
• Keep backup copies of your original DFT and intermediate DWG/DXF files.
