Adding DGN or DWG data

The CAD files in DGN and DWG format are frequently used to store drawings of engineering projects. A single DGN or DWG file can encompass line, point, polygon, and annotation layers. You can add DGN or DWG data in Event Editor using the following steps.


  • You need a DGN or DWG file and a PRJ (projection) file with the same name to add the data to the map.
  • The DGN or DWG file remains in the map until the end of the browser session.
