Export Bentley MicroStation Files (.dgn)

Use the MicroStation DGN exporter to export various types of data in your project, including lines, polylines, linestrings, arcs, circles, ellipses, splines, text, multilines, meshes, linear and angular dimensions, and block references in .dgn files that can be opened in MicroStation and other design tools, along with numerous field devices. This exporter, along with the DGN importer, facilitate seamless interoperability with Bentley products.

To access the exporter:

  1. Select Export in Home > Data Exchange.
  2. Click the CAD tab in the Export pane and select MicroStation DGN exporter.
