Understanding dgn and apr file formats
DGN is a file format used primarily by Bentley Systems' MicroStation and other CAD software for storing design data, such as 2D/3D drawings and models. It is widely used in engineering, construction, and infrastructure projects.
APR is an ArcView Project file format used by ESRI's ArcView GIS software. It stores project settings, layouts, and references to spatial data, but does not contain the actual spatial data itself.
Why convert dgn to apr?
Converting DGN files to APR format is useful when you need to integrate CAD design data into GIS projects managed in ArcView. This allows for enhanced spatial analysis and mapping capabilities using data originally created in MicroStation or similar CAD applications.
How to convert dgn to apr
Direct conversion from DGN to APR is not natively supported, as APR files are project files and do not store spatial data directly. The typical workflow involves importing DGN data into ArcView and then saving the project as an APR file. Here’s how you can do it:
- Use ArcGIS Desktop (ArcMap) or ArcView GIS to import the DGN file.
- In ArcMap, go to File → Add Data → Add Data... and select your DGN file.
- Once the DGN layers are loaded, arrange your map and project settings as needed.
- Save your project by selecting File → Save Project As... and choose the APR format if using ArcView GIS.
Best software for dgn to apr conversion
The recommended software for this process is ArcView GIS (for legacy APR support) or ArcGIS Desktop (ArcMap) for importing DGN files and managing GIS projects. Bentley MicroStation can also export data in formats compatible with ArcGIS if further preprocessing is needed.
Tips and considerations
- Ensure your DGN file is properly georeferenced for accurate spatial alignment in ArcView.
- APR files reference data locations; keep your DGN and other spatial data in accessible directories.
- For large or complex DGN files, consider converting to shapefile or geodatabase format before adding to ArcView.
