Convert DGN to OFF
Fast, free, and secure DGN to OFF conversion. No registration required.
A fast, free dgn to off conversion tool that works offline — your files stay on your device from start to finish. DGN MicroStation was designed for infrastructure design, civil engineering and utility mapping. By converting to OFF 3D Mesh, you unlock academic 3D geometry research and simple mesh interchange. This conversion bridges two ecosystems: Bentley Systems's DGN MicroStation and Geometry Center's OFF 3D Mesh. Xonvert automatically detects your source format — just drop any file and the converter configures itself.
Why Choose OFF Format for Your DGN Files?
There are strong reasons to convert DGN to OFF:
Metadata handling: OFF 3D Mesh has robust metadata support, allowing you to embed titles, tags, and descriptions that travel with the file.
Industry standard: In many 3d model workflows, OFF 3D Mesh has become the go-to format, making this conversion a frequent necessity.
API and automation: Many automated workflows and APIs expect OFF 3D Mesh as input, making this conversion necessary for programmatic processing.
Editing flexibility: OFF 3D Mesh files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens OFF 3D Mesh natively, reducing compatibility friction.

Conversion Quality Deep Dive
DGN MicroStation's known limitation — proprietary, limited support outside Bentley ecosystem — is resolved when converting to OFF 3D Mesh, which offers extremely simple format for basic 3D mesh data. The DGN MicroStation source uses lossless encoding. The OFF 3D Mesh output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient. Xonvert's conversion engine analyzes your DGN MicroStation source and selects the optimal encoding strategy for OFF 3D Mesh output. Supports 2D and 3D design data Optional per-vertex or per-face colors (COFF variant) These implementation details are handled automatically by the converter.
This is a cross-category conversion from CAD (DGN MicroStation) to 3D Model (OFF 3D Mesh). While these formats serve different purposes, Xonvert extracts the compatible data from your DGN MicroStation source and maps it into the OFF 3D Mesh format. CAD files typically contain infrastructure design, while 3D Model files are used for academic 3D geometry research and simple mesh interchange. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.

Common Questions About DGN to OFF
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target OFF format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
Does the conversion preserve metadata?▼
Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
Can I share the converted OFF file directly?▼
Yes. After conversion, you can download the OFF file and share it via email, messaging apps, cloud storage, or any other method you prefer.
Does converting DGN to OFF change the resolution?▼
Resolution is not applicable for cad files. All content data transfers at full fidelity.
Do I need to install any software?▼
No installation required. The converter runs entirely in your web browser. No plugins, extensions or desktop apps needed.
How do I know the conversion was successful?▼
Xonvert validates the output file and shows a success confirmation. You can preview the result before downloading. If any issue occurs, a clear error message is displayed.
Is batch conversion available?▼
Yes. Drag or select multiple DGN files and they'll all convert to OFF simultaneously. Download results individually or as a ZIP.
