Convert SKP to DGN

Understanding SKP and DGN file formats

SKP is the native file format for SketchUp, a popular 3D modeling software used in architecture, interior design, and engineering. SKP files store 3D models, textures, and scene information, making them ideal for conceptual design and visualization.

DGN is a file format developed by Bentley Systems for MicroStation and other CAD applications. DGN files are widely used in civil engineering, infrastructure, and construction projects, supporting both 2D and 3D design data.

Why convert SKP to DGN?

Converting SKP to DGN is essential when you need to transfer 3D models from SketchUp to MicroStation or other Bentley software for further editing, documentation, or integration into larger infrastructure projects. This ensures compatibility and seamless workflow between design teams using different platforms.

How to convert SKP to DGN

Direct conversion from SKP to DGN is not natively supported in most software. However, you can achieve this through an intermediate format such as DWG or DXF. Here’s a step-by-step method using SketchUp and MicroStation:

1. Open your SKP file in SketchUp Pro.
2. Go to File → Export → 3D Model and choose DWG or DXF as the export format.
3. Open MicroStation.
4. Use File → Import to bring in the exported DWG or DXF file.
5. Save the imported file as a DGN using File → Save As and select DGN as the format.

Best software for SKP to DGN conversion

• SketchUp Pro: Allows exporting SKP files to DWG/DXF, which are compatible with MicroStation.
• MicroStation: Supports importing DWG/DXF and saving as DGN.
• AnyCAD Exchange3D: A commercial converter that can handle SKP to DGN conversion directly for some versions.

Tips for successful conversion

• Check layer and material compatibility after conversion, as some data may not transfer perfectly.
• Clean up your SketchUp model before exporting to reduce errors.
• Always verify the DGN file in MicroStation to ensure all geometry and attributes are intact.
