Understanding DGN and IV file formats
DGN is a CAD file format developed by Bentley Systems, primarily used in MicroStation and other engineering design software. It is widely adopted in the fields of civil engineering, architecture, and construction for storing 2D and 3D design data.
IV stands for Inventor Visualization file, commonly known as Open Inventor format. IV files are used for 3D graphics and visualization, supporting complex geometry, scene graphs, and rendering attributes. They are popular in scientific visualization and 3D modeling applications.
Why convert DGN to IV?
Converting DGN to IV allows users to leverage advanced 3D visualization and rendering capabilities in applications that support the Open Inventor format. This is particularly useful for sharing engineering designs in interactive 3D environments or integrating with scientific visualization tools.
How to convert DGN to IV
Direct conversion from DGN to IV is not natively supported by most CAD software. The process typically involves exporting the DGN file to an intermediate 3D format (such as OBJ or STL), then converting that file to IV using a dedicated 3D conversion tool.
Recommended software for DGN to IV conversion
- Bentley MicroStation: Open your DGN file and use File → Export to export to a supported 3D format like OBJ or STL.
- MeshLab: Import the exported OBJ or STL file, then use File → Export Mesh As and select the IV (Open Inventor) format.
- Okino PolyTrans: A professional 3D conversion tool that supports a wide range of formats, including DGN and IV. Use File → Import for DGN, then File → Export to IV.
Step-by-step conversion process
- Open your DGN file in Bentley MicroStation.
- Export the file to OBJ or STL using File → Export.
- Open the exported file in MeshLab or Okino PolyTrans.
- Export the file as IV using File → Export Mesh As or File → Export.
Tips for successful conversion
- Check geometry and scale after each conversion step to ensure accuracy.
- Preserve material and color information by choosing the appropriate export options.
- Use professional converters like Okino PolyTrans for complex or large-scale projects.
