Convert DGN to DGR

Understanding dgn and dgr file formats

DGN is a CAD file format developed by Bentley Systems, primarily used in MicroStation and other engineering design software. It stores 2D/3D vector graphics, design data, and metadata for infrastructure projects. DGR files, on the other hand, are less common and are typically associated with Bentley's InterPlot software, used for plot set definitions and print management. DGR files contain references to design files, plot settings, and output instructions, but do not store actual design geometry.

Why convert dgn to dgr?

Converting a DGN file to a DGR file is often necessary for batch plotting or print management in large engineering projects. The DGR format allows users to define how multiple DGN files are printed, including settings for scale, paper size, and output devices.

How to convert dgn to dgr

There is no direct file conversion tool that simply changes a DGN file into a DGR file, as DGR files are plot set definitions referencing DGN files. Instead, you use Bentley's InterPlot Organizer to create a DGR file from one or more DGN files:

1. Open InterPlot Organizer.
2. Go to File → New to create a new plot set.
3. Use File → Add to add your DGN files to the plot set.
4. Configure plot settings as needed (scale, paper size, etc.).
5. Save the plot set using File → Save As and choose the .dgr format.

Best software for dgn to dgr conversion

The recommended software for this process is Bentley InterPlot Organizer. It is specifically designed for managing and creating DGR plot set files from DGN design files. InterPlot Organizer is part of the Bentley InterPlot suite, which is widely used in engineering and construction industries for batch plotting and print management.

Summary

To convert DGN files to DGR plot set files, use Bentley InterPlot Organizer. This process involves referencing DGN files within a DGR plot set, rather than converting the design data itself. This workflow is essential for efficient batch plotting and print management in large-scale engineering projects.
