About IFC and DGN

IFC

IFC (IFC BIM models) - Industry Foundation Classes - open BIM data exchange format for building information modeling. Best for bim workflows, architectural design, construction management.

DGN

DGN (MicroStation DGN drawings) - MicroStation DGN - Bentley Systems CAD design file for infrastructure projects. Ideal for civil engineering, infrastructure design, transportation projects.

FAQs

Is converting IFC to DGN free?

Yes, GoConvertFile offers free conversion of IFC to DGN for files up to 100MB. No registration required.

How long does it take to convert IFC to DGN?

Most IFC to DGN conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is DGN best used for?

DGN is ideal for civil engineering, infrastructure design, transportation projects. MicroStation DGN - Bentley Systems CAD design file for infrastructure projects

What file size should I expect after converting IFC to DGN?

File size after IFC to DGN conversion depends on the content complexity and quality settings. Both formats use similar compression approaches so sizes are comparable.

What is IFC?

IFC files are built around lossless compression. Designed for bim workflows, architectural design, construction management, they use the application/x-step MIME type and typically range from varies by content.

What is DGN?

DGN (Design) is the native file format of Bentley Systems MicroStation, used for storing CAD drawings and GIS data in infrastructure projects such as roads, bridges, and utilities, supporting 2D and 3D design elements with level-based organization.

When Should You Use IFC vs DGN?

Use IFC When...

Reach for IFC when your priority is bim workflows, architectural design, construction management — its uncompromising quality ensures every detail is preserved.

Use DGN When...

Reach for DGN when your priority is civil engineering, infrastructure design, transportation projects — its uncompromising quality ensures every detail is preserved.

IFC vs DGN: Key Differences

  • •IFC and DGN diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: DGN lacks transparency support.
  • •Storage footprint: varies for IFC vs 100KB to 1GB depending on design complexity for DGN.
  • •Use case fit: IFC targets bim workflows, architectural design, construction management and DGN targets civil engineering, infrastructure design, transportation projects — your choice depends on which workflow stage you are serving.

Advantages of IFC

  • ✓IFC applies lossless compression specifically calibrated for BIM workflows, architectural design, construction management.
  • ✓IFC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓IFC guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find IFC support built into virtually every tool that handles BIM workflows, architectural design, construction management — no plugins or converters needed.

Common Use Cases for IFC to DGN Conversion

Industry Applications

Best Practices for IFC to DGN Conversion

  • →Test a single file first before converting multiple files
  • →Check the output quality on your target device or platform
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting IFC to DGN Conversion

  • !Converting IFC to DGN failed → check if the source file is valid and not corrupted
  • !DGN output looks unexpected → try different conversion settings or reduce file complexity
  • !File size changed dramatically from IFC to DGN → this is normal when converting between lossy and lossless formats
